How do I disable attendees from adding AI Notetakers (otter.ai, read.ai, fireflies.ai, etc.) to our Webinars

Attendees have been joining AI notetakers to our company webinars, and I am trying to prevent this from happening. 

I don't want to manual remove them during the live session. In the account settings I have blocked as domains Read.ai, Otter.ai. 

Do you have any recommendations?
