Hi,

I'm trying to implement a custom workflow which runs on the branch of the PR where the command was triggered.

My trigger looks like this:

name: Dispatcher
on:
  issue_comment:
    types: [created]

jobs:
  slashCommandDispatch:
    runs-on: ubuntu-latest
    if: ${{ github.event.issue.pull_request }}
    steps:
      - name: Slash Command Dispatch
        uses: peter-evans/slash-command-dispatch@v2
        with:
          token: ${{ secrets.REPO_PAT }}
          allow-edits: true
          reaction-token: ${{ secrets.REPO_PAT }}
          permission: write
          dispatch-type: workflow
          ref: ${{ env.GITHUB_REF }}
          commands: |
            test

If I write /test in my PR it'll trigger the dispatcher and also the action which listens on the Event but it will alway use the main branch. Is there a way to use the PR branch? As you can see I tried using the ref argument but thats not recognized.

My custom action to be triggered looks like this:

name: Testing

on:
  workflow_dispatch:

jobs:
  jest:
    name: Run Jest
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

I verfied that the commit hash was wrong in the GitHub UI:

This commit is from the main branch and not from my PR:

Expected behaviour would be, that it checks out the branch which is associated with the Pull Request where I typed the command. Is this even possible?
