Is there a way to add a custom prefix to an axum route serving tonic grpc-web?

[frederikhors]

I need to use a "prefix" for grpc routes... I'm using Axum like:

let mut api = Router::new().route(
    "/api",
    on(MethodFilter::GET | MethodFilter::POST, my_api),
);

api = api.route(
    "/grpc/players.PlayerService/*endpoint", // I need the prefix "grpc" here as you can see
    axum::routing::any_service(grpc_server),
);

Is there a way?
