more space in a group chat

I have a friend group of 11 people who talk in one group chat. the problem is that you can only have a maximum of 10 people in one. We have already tried to message each other on a server but then the owner has a lot more power than the rest.

You might ask, there is also an owner in a group chat. You see in a group chat the owner can only kick other people, while in a server you can make different roles. Giving other members permission to kick/mute.

I think you could make a boost system (like the ones you have on servers) where you boost a group chat. A boost would open the invite ballet for 10 more people to join. A boost would last a week (to not make it too overpowered) and when the boost is over, only the members already in the group chat can stay.

An example would be, I boost a group chat that has 10 members. Then i invite 3 more people to the group chat. Meaning there are a total of 13 people in the group chat after the week is over. Then you cant invite more people in and if someone leaves then it would be 12 people max in the group chat.
