I want to use my surface pen with onenote online (mainly to be in teams and use onenote within teams). However, the stylus input from the surface pen isn't recognized like it is in OneNote for windows 10 or OneNote desktop. Therefore, I need to use the draw toolbar and select the tool, then switch back and forth between typing/draw/erase.

I have been recently using kami for my classes in google classroom, and whatever web application they made recognizes my surface pen as a stylus and switches finger input to pan, and stylus to draw automatically. It even recognizes my surface pen's eraser as an eraser. Not sure how they do it, but it would be great for use in office online applications. Onenote, word, etc. Especially for giving feedback with in teams assignments and for using class notebook within teams.
