how to use buttons to control pico play #5

I tried to add buttons to control the play and pause of music. I added gpio interrupt detection in the main function, but it did not work correctly. Does interrupt conflict with bluetooth? Or I should write this button control somewhere else

Interrupts don't conflict with bluetooth, but there are generally many restrictions what you can do in an interrupt. So, e.g. just set a play flag on button press in the interrupt. In main loop check the flag. If it is set, do the play function and reset the flag. That should work.
