How can I limit the number of participants in breakout rooms?

I’m not programmer.
I make free events using jitsi meet.
I need to split users to breakout rooms. Maximum number of users in one room is 6.

I’ll try to explain using example:
I send link to jitsi room to 30 users and I need to jitsi split them into 5 breakout rooms with 6 participants. For example when 7th user opens my link he will get into 2nd breakout room.

Could someone help me?

There is no such feature. The moderator that is in the meeting can do the distribution of people.
