Hi everyone,

This is more of a question for everyone. I want to run GitHub Action on the forked repo for a particular PR. The action should push something on the forked repo before merging the PR. Is this possible?
I know that the base repo will not have the permission to push in the forked repo so we need to run the actions of forked repo for this use case. So how could we do that?

I was trying with the following yaml:

name: Actions-CI
on:
  issue_comment:
    types: [created]
jobs:

tests:

if: contains(github.event.comment.html_url, '/pull/') && startsWith(github.event.comment.body, '/run-e2e')

runs-on: ubuntu-latest

steps:
  #Using the last commit id of pull request
  - uses: octokit/request-action@v2.x
    id: get_PR_commits
    with:
      route: GET /repos/:repo/pulls/:pull_number/commits
      repo: ${{ github.repository }}
      pull_number: ${{ github.event.issue.number }}
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

  - name: set commit to output
    id: getcommit
    run: | 
       prsha=$(echo $response | jq '.[-1].sha'  | tr -d '"')
       echo "::set-output name=sha::$prsha" 
    env: 
      response:  ${{ steps.get_PR_commits.outputs.data }}

checkout on the lastest commit
  - uses: actions/checkout@v2
    with:
      ref: ${{steps.getcommit.outputs.sha}}

setup golang
  - uses: actions/setup-go@v2
    with:
      stable: 'false'
      go-version: '1.14.0'

run embedmd (this will write something in the file)
  - name: Installing and Running embedmed
    run: |
      go get github.com/campoy/embedmd
      cd docs
      embedmd -w $(find *.md)


  - name: Commit files
    run: |
      git config --local user.email "githubactions@github.com"
      git config --local user.name "Myname"
      git commit -s -m "Run embedmed" -a
  - name: Push changes
    uses: ad-m/github-push-action@master
    with:
      github_token: ${{ secrets.GITHUB_TOKEN }}

Thanks !
