Bangle companion app

hi, anyone any idea how to control the phone from the watch?

what i think is, the phone have much more sensors, so it is the base.
it will sit in my chest's pocket, with either front or rear camera facing my front.
the mics, +/- headphones will be ON, together with wifi, bluetooth, GPS etc.

Since i am an AI guy,
i would like to see the watch either

1. act as a small window to the android's screen, and allow you to use the watch's screen as touchpad and click (VNC?)
   
   

OR

1. press a virtual button on watch and call up some apps on the android, esp press a virtual button and call up openai.app or the web version, together with voice input and speaker/headphone output. then i'll have a servant 24x7 for me.
   
   
   

thank you.
