Hello, I am trying to use AD5933 by connecting it to esp32.
However, I connected SDA, SCL 21,22 GPIO and also used a 4.7K resistor,
but I cannot find it in the AD5933 library.
I tried to find AD5933 through I2C Scanner,
but it doesn't show up either.
I've been going crazy for 4 days. Please help me.

the one?
Please show the schematic and the I2c scanner code

I am highly suspicious you have wired it wrong. I know doing an annotated schematic is a pain but without it we can spend weeks taking guess as to what your problem is. You may have to spend some time with a CAD (Computer Aided Design) Program if you do not want to do it by hand and/or if you eventually want to build more.
Posting an annotated schematic showing exactly how you have wired it helps us help you. By showing all connections, power, components, ground and power sources you will save a lot of clarifying questions and time for all of us. Be sure to note any logic wires over 10/25 inches/cm in length. Post links to technical information on the hardware items including the motors, shield, and Arduino. This should include all component values or model numbers and details of all power supplies used (which could be USB power for example). Posting the code following forum guidelines using code tags will also help. With this information we should be able to answer your question accurately. "How to get the best from this forum".

If you don't understand what a schematic is, please Google to find out. It is not the same thing as a wiring diagram. Hand-drawn is OK. Some bright, sharp photos of the circuit may also be useful.
The thing I see is many of the users do not want to draw schematics yet a large portion of there problems are in the connections, power etc. It appears they spend about a week or so with lots of questions and then maybe, give up, and some get lucky. It is amazing how many problems you find when doing a real labeled schematic including Technical links. That schematic makes them look like a pro.
It appears to me that most of the time when a proper schematic is posted the solution is usually within day or so. Good schematic capture software can be gotten for the downloading. Months later a wire comes off, looking at the schematic and putting it back saves lots of headaches.

KiCad: There are many out there and you will find just like color different people like different colors, some blue, red, ..etc. CAD (Computer Aided Design) programs are like that. You will need to learn a schematic capture program that will work for you.
I work from schematic capture through a set of Gerber files that the PCB will be made from. I have a limited budget and I use KiCad but there are many others available. It is not a program you will learn in an evening or so, nor or the others. There are a lot of resources available, on line, all free same as KiCad. If you download KiCad they will ask for a non required donation. It works great on Linux, I have had it run on the last 5 versions of mint. As I understand it it also works on a Mac and Win-doze machines as well.
The hardest part is finding the parts, there are a thousands of different ones available with the more popular included in the install. It has a 3D viewer which is handy. If I am making a schematic and I cannot find the part configuration, I take something close to it and edit it to what I want. Starting with a box and adding pins is not that hard.

Download your choice, KiCad maybe and play with it. Do a few simple designs and get a feel to how it works. It is a full hierarchical CAD program but you do not need to use those features, all my schematics are generally one page. Here is what they say:
KiCad's Schematic Editor supports everything from the most basic schematic to a complex hierarchical design with hundreds of sheets. Create your own custom symbols or use some of the thousands found in the official KiCad library. Verify your design with integrated SPICE simulator and electrical rules https://www.kicad.org/
