UNO R4 WiFi and display for Atmega328P board

Hardware UNO R4 UNO R4 WiFi

Hello!
Excuse me for the question, so basic: I'm a newbie on Arduino.
I'm working on a project that needs to output some text on a display a bit larger than classic 0.91" or 1,.." you can easily find, but they are too small.
I found an interesting " AZDelivery LCD Display 128 x 64 pixel 12864 Display KS0108/KS0107" (https://www.amazon.it/gp/product/B07YY7MGV4/ref=ask_ql_qh_dp_hza) that could be big enough for my needs.
I downloaded the documentation from the producer website and about connecting it to Arduino says "Connecting display to Atmega328P Board": this stands for "It's not compatible with UNO R4 Wifi"?
If yes, could someone suggest a display of same dimensions or a bit smaller and compatible with the UNO R4 Wifi?

Many thanks in advance

Just some 1602 LCD for text is fine.

Thanks for your reply.

I just received an HD44780 1602 bundle di display del modulo LCD con interfaccia I2C 2x16 (az-delivery.de), I would like to check avoiding soldering now (so if it doesn't work fine I can return it without modifications).

Libraries from the manufacturer website (https://cdn.shopify.com/s/files/1/1509/1638/files/Arduino-LiquidCrystal-I2C-library-master.zip?13767300524400922353) and from GitHub - Testato/PCF8574_HD44780_I2C: PCF8574+HD44780 LCD I2C Arduino Library are working well both: compiled and uploaded correctly.

I tried to connect the display to SCL and SDA at ports SCL and SDA on the Uno R4 Wifi and also on A4 and A5.

Output is always the following showed in photo. It's beacause pins are not yet soldered or do you think there are other issues?

The display looks ok, but you'd need to solder the PCF8574 board to it, otherwise it will not work.
