Will merge queue workflows not run if a PR is merged using github.token?

Body

I have a repo with the following:

• allow auto-merge enabled
• branch protection on main with merge queues enabled and a few required status checks
• workflow A triggered on: push (to a specific branch)
  • this workflow creates a PR with target branch main and then marks for "auto merge" (via. gh pr merge --squash --auto <PR-num>)
• workflow B triggered on: pull_request and workflow C on: merge_group
  • these workflows run jobs that provide status checks for statuses marked as required in main's branch protection rules

Workflow A seems to be working correctly: a PR is created and then marked for "auto-merge". Once status checks pass (courtesy of workflow B), and a code owner Approves the PR, the PR is added to the merge queue... however, workflow C doesn't seem to get triggered (eg. I see no new workflow runs for merge_group events).

In this scenario, will workflow C never get triggered because of the "workflows cannot trigger other workflows by default" restriction (https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/triggering-a-workflow#triggering-a-workflow-from-a-workflow) even though the PR doesn't immediately enter the merge queue when workflow A completes?
