GitHub Actions bot trigger

When an action is set, such as adding a label x1 to an issue, Actions will automatically add a label x2 to the issue.

But if this is done by GitHub Actions bot (that is, the token in the actions is not passed, or the default token: ${{ secrets.GITHUB_TOKEN }} is used), the actions of label x2 will not be triggered.
