How to configure PullApprove to send requests to a subset of a team that can submit approvals?

I'm using PullApprove v3 for GitHub PRs. I have a larger team general-team and a smaller team specific-team. specific-team is a subset of general-team.

I want to allow PR approvals from anyone on general-team but only send requests to specific-team to avoid spamming general-team.

I found in the PullApprove documentation that I can prefix a team with ~ to exclude them from receiving requests. My .pullapprove.yml looks like this:

version: 3

groups:
  code:
    reviews:
      required: 1
      request: 2
    reviewers:
      teams:
      - specific-team
      - ~general-team

But because specific-team is a subset of general-team, they are marked unavailable and no requests go out. How can I send requests to specific-team?

Some people use optional groups + overrides (and reviewed_for) to do this. Something like this:

version: 3

overrides:
- if: len(groups.approved.include("global-approvers")) == 1
  status: success
  explanation: 'Passing as globally approved by global approvers'

groups:
  code:
    reviews:
      required: 1
      request: 2
    reviewers:
      teams:
      - specific-team
  
  global-approvers:
    type: optional
    reviews:
      request: 0
      required: 1
      reviewed_for: required
    reviewers:
      teams:
      - general-team
