+If you want to use this action from a workflow file that doesn't run on the `pull_request` or `pull_request_target` events, use the `pull-request-number` input:

+jobs:
+  auto-approve:
+    runs-on: ubuntu-latest

+```

 ## Why?
 
 GitHub lets you prevent merges of unapproved pull requests. However, it's occasionally useful to selectively circumvent this restriction - for instance, some people want Dependabot's automated pull requests to not require approval.
