+A solution to [How to merge branches on github.com without doing pull request?](https://stackoverflow.com/questions/24276409/how-to-merge-branches-on-github-com-without-doing-pull-request) using `actions/github-script@v5`, see [here for action](https://github.com/JEFuller/merge-deploy-action-demo/blob/26df2e798b74782bcb1be586024cdcdd984b2440/.github/workflows/update-other.yml#L7-L19).

+Note: if you have e.g. a [`deploy.yml`](https://github.com/JEFuller/merge-deploy-action-demo/blob/26df2e798b74782bcb1be586024cdcdd984b2440/.github/workflows/deploy.yml) with an `on: push` it will not be trigged (since `updateRef` isn't technically a `push`).
+
+
+But that can be triggered automaticall using `actions/github-script@v5`, see [here](https://github.com/JEFuller/merge-deploy-action-demo/blob/26df2e798b74782bcb1be586024cdcdd984b2440/.github/workflows/update-other.yml#L21-L32).
+
+Note: the deploy workflow will need to be updated to `on: [push, workflow_dispatch]`:
