Notifications about Channel Meetings

Dear all

I wonder can you help. I am a head of Department in a school that is moving all our teaching online. I have been instructed to get my self added to every class team in my department (over 60 classes). This is so I can keep an eye on what is going on and also support people who need it.

I have hidden all these teams and I thought that turned the notifications off. People have started scheduling meetings for their classes for next week and I am getting notifications about all of these and Calendar invites for them. 

Is there anything I can do to silence this?

Thanks

Ashley
