 - Use the default `GITHUB_TOKEN` and allow the action to create pull requests that have no checks enabled. Manually close pull requests and immediately reopen them. This will enable `on: pull_request` workflows to run and be added as checks. To prevent merging of pull requests without checks erroneously, use [branch protection rules](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests).

It's advisable to use a dedicated [machine account](https://docs.github.com/en/github/site-policy/github-terms-of-service#3-account-requirements) that has collaborator access to the repository, rather than creating a PAT on a personal user account. Also note that because the account that owns the PAT will be the creator of pull requests, that user account will be unable to perform actions such as request changes or approve the pull request.

+### Show an annotation message for a created pull request
+
+Showing an annotation message for a created or updated pull request allows you to confirm the pull request easily, such as by visiting the link. This can be achieved by adding a step that uses the [`notice` workflow command](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/workflow-commands-for-github-actions?tool=bash#setting-a-notice-message).
+
+For example:
+
+```yml
+- name: Create Pull Request
+  id: cpr
+  uses: peter-evans/create-pull-request@v7
+
+- name: Show message for created Pull Request
+  if: ${{ steps.cpr.outputs.pull-request-url && steps.cpr.outputs.pull-request-operation != 'none' }}
+  shell: bash
+  env:
+    PR_URL: ${{ steps.cpr.outputs.pull-request-url }}
+    PR_OPERATION: ${{ steps.cpr.outputs.pull-request-operation }}
+  run: |
+    echo "::notice::${PR_URL} was ${PR_OPERATION}."
+```
+
+In this example, when a pull request is created, you will be able to see the following message on an action run page (e.g., `/actions/runs/12812393039`):
+
+```
+https://github.com/peter-evans/create-pull-request/pull/1 was created.
