question regrading minApprovals authorAssociation

[xli1996]

Hi, maybe I do not fully understand the document, in the example in README
https://github.com/bobvanderlinden/probot-auto-merge#minapprovals-required-condition

In the example below when a pull request gets 2 approvals from owners, members or collaborators, the automatic merge will continue.

minApprovals:
  COLLABORATOR: 2

However, when I tried on a private repo, the PR get approved does not get merged due to

    "minimumApprovals": {
      "status": "fail",
      "message": "There are not enough approvals by reviewers"
    },

And I search on graphql find that

        "reviews": {
          "nodes": [
            {
              "authorAssociation": "CONTRIBUTOR",
              "author": {
                "login": "****"
              },
              "submittedAt": "*****",
              "state": "APPROVED"
            }

I wonder does the reviewer's authorAssociation has to match what in minApprovals. Is there anyway to auto merge if there is any approval without authorAssociation? I think it could be done by setting branch protection rules, but I wonder if the pro-bot may capable of it as well.

CONTRIBUTOR is considered a lower association than COLLABORATOR. You can accept any approvals using NONE: 2. Any approvals is not recommended for public repos as it would allow anyone to merge a PR.
