Chess.com Coaching

Can anyone provide some tips for using Chess.com for coaching?

Is it possible to highlight squares, draw arrows etc., so that an opponent can see them?

when u say that do u mean as in on an analysis board

I mean is there a way to communicate with someone when playing a live game that is better than short text messages.

Being able to expose arrows etc. would be ideal.

apart from the in game chat i dont think that there is another way. 

So I guess Zoom with shared screen?

Does anyone receive coaching using chess.com - how do you work?

i used to recieve coaching from friend, but we just texted eachother as in on phone and used teamspeak

Good coaches use zoom and split screen, employing the chess.com virtual boards.
