I have a TC26 with android 11, and I would like to remap the L2 button to turn the screen on AND off.

I can turn on the screen using "Wake-Up Sources", but to turn off, I still have to press the power button.

To solve this, I could remap the L2 button to the power button in android 10, but this doesn't seem to work in android 11. "Power" had disappeared from the options.
