Discussed in #120

Config file:

reviewers:
  # The default reviewers
  defaults: # currently defaults to the default reviewers.  Will randomly assign one of them (or 2 depending on "number of reviewers" config)
      - team:mds-platform
      - crockhill_sfemu

  groups:
  #MDS-Platforms  
      mds-plaform-approver:
        - crockhill_sfemu

  per_author:
  # MDS Platforms Review Assignments
      mds-plaform-approver:
        - team:mds-platform


  options:
    ignore_draft: true
    ignored_keywords:
      - DO NOT REVIEW
    enable_group_assignment: true

    # Randomly pick reviewers up to this number.
    # Do not set this option if you'd like to assign all matching reviewers.
    number_of_reviewers: 1
    #update

    # If it's true, the last matching files-change pattern takes the most precedence (CODEOWNERS-compatible)
  
    # last_files_match_only: false

It also took me quite a few runs to figure out a setup that works.
I did the following:

• Create a PAT (personal access token) scoped to the repo with the following permissions:
  • Members: read and write, Team discussions: read and write, Metadata: read-only, Pull Requests: read and write
• make sure your team name is correct
• modify your action checkout the repo and use a local config as the token has no access writes otherwise (might also be controllable via another permission, but didn't dare to try)
  Here is what my action ended up looking:

on:
  pull_request_target:
    types: [opened, ready_for_review, reopened]

jobs:
  assign-reviewer:
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v4
        - name: Auto request review
          uses: necojackarc/[email protected]
          with:
            token: ${{ secrets.TOKEN_TEAM_ASSIGNMENT }}
            config: .github/reviewers.yml
            use_local: true

Hope that helps!
Plus for testing make sure you add pull_request as a trigger for your action otherwise the changes to your yml might not get picked up.
