Limit # participants in different modes in a hybrid webinar

What are you trying to do? (Detailed description)
Limit the number of participants that can follow the event being physically present apart from the number of participants that can follow the event from home/the office for a hybrid event.

What is the challenge you’re experiencing?
As our room capacity is limited and as we have to take into account the actual Covid-19 regulations, we need to limit the number of participants that can follow the event physically at the event location apart from the number of participants that can follow the event from home/the office.

Do you have a workaround that you use right now?
Follow the choice of people that sign up manually and very closely.
