You could follow the same steps but with several additional:

1. Install the package Microsoft.AspNetCore.Grpc.HttpApi This is going to map your gRPC endpoints to the classical HTTP. It is not automatic you need to specify the services in the Startup.cs as follow:

    app.UseEndpoints(endpoints =>
            {
                endpoints.MapGrpcService<MygRPCService>();
            });

2. Into your protos you need to indicate the HTTP path, something like this:

     rpc Get(GetRequest) returns (GetReply) {
        option (google.api.http) = {
          get: '/my-endpoint'
          body: '*'
        };
      }

3. Add to your Startup.cs ConfigureService method:

    services.AddGrpc();
    services.AddGrpcHttpApi();
