Another issue, I cannot change the volume on my M5stack Plus. Some help?

Thanks, you are a machine and fast.

I am using M5stickc plus at the moment I am very happy with them, but I have had a problem and I cannot find a solution.
I am unable to make a beep sound and I am not listening because, I am attaching the code to see if they can help me.

Thanks in advance.

Is it possible to use the "painlessmesh" library in the M5Stack Core 2 or M5Stick Cplus for Arduino IDE?
I am having trouble compiling it to arduino, it is very necessary for me.
Thank you
