Branches pattern with wildcard as prefix & suffix

on:
  pull_request:
    branches:    
      - '**prod**'

Using the above code seems not possible for us, does it currently not supported?

Turns out, the targetted branch is not a default branch, and no workflows added (exist previously) in the targetted branch, making it unable to trigger any pull_request event

Thanks for sharing the outcome @mochadwi as it will help other users who might have the same question.
