More Capacity of private group calls

Hey Discord Team

can you pls raise up the capacity of group calls to 20 or more. I ask you that because we are a friend group of more than 10 people and we dont like to create a server, we want our a privacy. And the feautures are better in a private call, for example the ring feauture and if the number raieses up, we can use Discord in School because you can compare the private calls with Zoom-Meeting but with the feauture, one time created: Using forever.
