Akka gRPC IDE Support?

I have become quite a fan of Akka gRPC for simple gRPC use cases. However, for more complex use cases (nested message types for example) it appears to confuse IntelliJ and Metals to the point where they’re both quite unusable (Scala). Imports don’t work for some reason even though the compiler seems to know about them.

I’m wondering if there is some workaround that the Akka community has come up with for making auto imports, type highlighting, and auto-generation of abstract methods that need to be overridden. These features are quite important to why gRPC is so productive to code in.
