ACL/Meniscus Surgery to Teaching

Hi there, I recently got ACL and meniscus surgery in June and I have been slowly strengthening my knee in rehab looking forward to returning to the mats. An opportunity has come up to teach some beginner classes to youth at a local community centre. I am wondering when it would be safe to teach a class. I will be in consultation with my PT but he doesn't do jiu jitsu so it's kind of hard to explain. I would only be showing the students the techniques and leading a warm up, not participating in any of the live sparring. What are you thoughts on this?
