The output of minitouch is like this:
open: Permission denied
Unable to open device /dev/input/event2 for inspection
open: Permission denied
Unable to open device /dev/input/event0 for inspection
open: Permission denied
Unable to open device /dev/input/event1 for inspection

The event0, event1 and event2 are in the system group, does it mean minitouch cannot run on this device? any workaround way?

Any suggest is appreciated, thanks in advance.

Have you resolved this problem? My RedMi Note 8 Pro also failed, the same problem with yours.

Have you tried to use shell in superuser mode?
