Using a mouse and micro controller to send X and Y data to Quest 2/ Quest controller, how do I even?

Hey!
So, I know very basic C++/Arduino and I can easily make a sketch that takes the values X and Y of the mouse and apply them to [for example] a couple of servos.

My question is how do I communicate/send those values to the Quest and interpret them to locomotion?

I figured that since the Kat-walk slide-mill can send data to the quest and be recognised as locomotion, I should be able to do something similar. 🤔

I plan on using a ESP32 micro controller for the built in Bluetooth to hopefully keep it wireless.

Any help is appreciated.
