Toutchscreen support?

[DerOptiker86]

Hi there world and builders!
I set up a new RP 4 with the MM. I like to use it with a toutchscreen only (without a mirrorglas in front of it).
Is there anybody who knows a module or something like this?
Whats my goal: put it on the wall and i like to leave a note on it for my girlfriend or a remindertext for later.
The touchscreen has a pencil with it.

Thx and best regarts from germany!
Stay save and healthy!
