Certain operations on commits and pull requests requires that the issuer has "integrator" status in the repository. This is a concept in the PullRequestBot. Specifically using the /tag command on a commit or performing merge style PRs fall into this category (though the latter only requires it if the integrators set is non empty).

The problem with this is that there is no way of actually configuring the set of integrators. When these checks were added, the integrators concept was added to PullRequestBot and PullRequestBotBuilder but not PullRequestBotFactory, which is responsible for parsing the config file.
