zoom cloud meetings – Use an Android tablet as a Wacom drawing tablet for a Mac?

You can do so using the Android remote control software scrcpy:

If you enable Development option on your Android device and afterwards enable the “Android Debug Bridge” option you can connect your Android device to your computer via USB and then remote control the Android device and see it’s screen on your computer using a software like scrcpy (install it on MacOS via brew install scrcpy).

Then in a Zoom call you can share your computer screen which shows the Android screen via scrcpy.
