Sonic pad with ender 3 Max neo

Can anyone help me get my ender 3 max neo to work with the sonic pad? I am a complete newbie and have very little to no knowledge regarding computer hardware and configuration files.

At this point the stupid thing is an expensive paperweight. I can’t get the sonic pad to work and the original display that came with it won’t connect either.

Please. Looking for idiot proof instructions.

Thanks so very much!
