How to run gRPC requests in sequence for Automation?

My question:

How to run gRPC requests in sequence(wokrflows) for Automation proposes?
If there is no way then when it is expected?

I’ve already tried:

  1. I added several gRPC requests and tried to Run Collection.
    I do not see Run option on Collection with gRPC requests.

  2. I tried to use postman.setNextRequest(); in AfterResponse script
    But I receive ReferenceError: postman is not defined
