Ability to pick display to mirror?

[wasabi-peanutz]

Could you add support for the ability to choose a display to mirror?

Per scrcpy feature:
If several displays are available, it is possible to select the display to mirror:
scrcpy --display 1
The list of display ids can be retrieved by:
adb shell dumpsys display # search "mDisplayId=" in the output
The secondary display may only be controlled if the device runs at least Android 10 (otherwise it is mirrored in read-only).

I would like to mirror the dex mode on my samsung!
