This is a subject I've been interested in the last couple of weeks, having been abruptly transitioned from being an in-person piano teacher to an online one, and wanting to achieve the very best audio in my online lessons.
With all the right settings, Zoom can be good enough for my purposes, but i doubt it would suffice for yours. I hear that Cleanfeed is the way to go and have heard excellent examples of the results achieved: https://cleanfeed.net/
But be aware Cleanfeed does not support mobile devices at present.
Another option could be live YouTube streaming.
