Hi guys,
We are using `nakama-js` with `nakama-js-protobuf` adapter because our protocol operate on protobuf.
I have a question how to integrate our `.proto` files with websocket protobuf adapter. I see how to update nakama `.proto` files `api` and `rtapi`, but in this solution must create new package based on the existing one, is there any other/better way?

This is not something that’s possible - the Nakama-protobuf library only works with Nakama API and that cannot be extended.
