Can't see class generated by grpc from Java .proto file?

Question

Java

I don't see the classes I should be seeing (at least I think so). I understand grpc. Generated class from .proto file. Everything in the class is public. But I can't see this package. Attached is the structure of the project. From the block that I highlighted in red, I'm trying to call functions from the green block.
For example, I tried to call the public function "DummyServiceBlockingStub"

I tried to manually write "import com.proto.dummy.Dummy.ServiceGrpc;" - does not see package "proto"
