+An example workflow to push to a protected branch inside your own repository. Be aware that it's necessary to use a personal access token, and maybe it is a good idea to specify the force-with-lease flag in case of sync and push errors:
+
+```yaml
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+        with:
+          ref: ${{ github.head_ref }}
+          fetch-depth: 0
+          token: ${{ secrets.PAT_TOKEN }}
+      - name: Commit files
+        run: |
+          git config --local user.email "test@test.com"
+          git config --local user.name "Test"
+          git commit -a -m "Add changes"
+      - name: Push changes

+        with:
+          github_token: ${{ secrets.PAT_TOKEN }}
+          repository: Test/test
+          force_with_lease: true
