Real Time Supervision Log-in

I am working from home today and one of my supervisees is in the office seeing a new client. His intake paperwork was concerning. We have a supervisor there in his own session, so she is not there alone. However, I wanted to login to her session to see the sentiment of it as I am just concerned for her. This does not look like an option, however it could be helpful in situations like this if it could be. I just wanted to share my dilema, Thank you guys!
