OTG Cable - no connection / power

I have an arduino uno and a xiaomi redmi note 9 pro phone. I am trying to connect it via an OTG cable (I did it myself) but there is NO reaction. Does not put tension on the arduino. I connected 4 cables (+, -, data +, data-) according to the drawing. And there is NO reaction, no electricity. "Cable USB B" and "device USB A"
usb-connectors
WTF?

What does 'WTF?' mean?

Have you googled how to make the OTG cable? Did you follow what it said?

in USB type B what is used for Arduino connection to the PC there are 4 wires like in USB typa A. So i maded these cable to connect to handy. Sorry for bad name, but thats simple 2 cables (one female, second male 4 wires and thats all) and it is NOT WORKING. Do you know any other 5,6,7 wiring cables USB type B ?
