How to connect protobuf schemas with contol-center

Question

While working on some of our services in our project, we integrated protobuf into our design, so currently all our services communicate through kafka topics, each topic has its protobuf schema related to it.

we are trying to publish events directly to each topic but they are not formmated with protobuf decoding.

Is there any way to "load" schemas onto the "schemas" tab in control center?

Below there is the kafkas services in our docker-compose.yml file:
