title: Github actions merge specific pull request
body: <p>What i need is to merge a pull request opened previously by the same Github Action, but i need to merge only that specific pull request as for example if x is editing file y in feature 1 and open a pull request i don't want that one to be merged. If the Github actions create a pull request as in the example below i need it to merge only the one created by itself or by specific pull request name.</p>
  <p>Are there any solutions to this?</p>
  <pre><code>merge-branch:
      if: ${{ github.event.label.name == 'commit' }}
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@master
        - name: test1
          uses: devmasx/merge-branch@v1.3.1
          with:
            type: now
            from_branch: feature1
            target_branch: master
            github_token: ${{ github.token }}
  </code></pre>
