Recommend software for connecting to pilots flying in MSFS and sharing comments?

I have software app (MSFS addon) that is almost ready for testing. The app is
very large and I think it will require an hour tutorial , which I’d like to do
witth the pilot flying and myself able to comment and guide them acting as co-
pilot (which is what the software does). Can anyone recommend software that
would allow me to share a session and tutor MSFS pilots in flight? thanks
