Please share the firmware for the steering wheel ESP32

Hello, racers
Since I don't have the proper programming skills, I'm trying to find an ESP32 firmware for my gt3 steering wheel. I would like to use a matrix of buttons and 4-5 rotary encoders. The problem is that I can't find a firmware that could completely cover these 2 of my needs.
https://github.com/lemmingDev/ESP32-BLE-Gamepad

I was trying to make a 4x5 button matrix using this. With the help of diodes, I was able to make all the buttons work at the same time, but I can't integrate rotary encoders in any way
Next, I worked with a ready-made firmware
https://github.com/MagnusThome/ESP32-BLE-Gamepad

The matrix and encoders work well. But unfortunately, only 1 pressed key is registered, no more. I think this strict restriction on the number of keys pressed can be removed by changing some variable. However, after a night of diligent searching, I couldn't find her and gave up

Next, I found a cool project with an interface
https://gitlab.com/realrobots/rr_configurator
This project allows you to combine several microcontrollers into one device and connect very, very many buttons and configure all outputs using rr_configurator. I was so glad I found this. With this firmware, you can use an unlimited number of simultaneous clicks in the button matrix, even without using diodes. But if everything was fine, then I wouldn't ask you for the firmware. Unfortunately, I, as well as some other people, have problems reconnecting. I won't bore you with the details. I will only say that the author does not have time to finish this project.

I also tried to configure other firmware, but it always turned out to be a similar situation. It didn't have either encoders, a button matrix, or a bluetooth problem. I'm starting to think I'm under a curse, no other way

I went to the forum to ask for information, where can I find the firmware for ESP32 with a matrix of buttons and rotary encoders?
Maybe some people will be extremely kind and will be able to disable the registration of only one key in the second sewing

I believe the LemmingDev software will work. Hope to try this myself in the near future.

I can share this if it helps and i could use help on how to wire the buttons
