Developer Mode - Android Apps - Documentation on iteraction methods?

Hi support team,

I'm testing traditional Android apps on Meta Quest 3 to solve some of my needs (specifically remote desktop at this time). I was able to install and run some apps. However, I'm confused when it comes to app touch input. Is there documentation explaining how controllers and direct touch works with Android apps? So far I've found this:

B = back button
A = tap where the pointer is
Trigger = tap where the pointer is
2 triggers + move controllers - pinch-zoom

I tried coming closer to the screen and tapping with 2 fingers at once - this doesn't seem to have any effect. Can you confirm? While testing NoMachine Client app, I was able to do right click (done with 2-finger tap) only once, and I did not understand how I did it. Can you provide some guidance? Can I do 2 finger tap with controllers or hands? What about 3 finger, 4 finger?

Additionally, can you please allow resizing windows in "Near" view just like they can be in "Far" view?

Essentially I'm looking for a direct-touchable remote desktop, and the issues mentioned above really limit my options.
