Skip if there are newer runs

I have a quite huge integration test suit and would like to cancel it if at least one newer run is scheduled/in progress.

Is something like this possible?

jobs:
  skip_individual_steps_job:
    runs-on: ubuntu-latest
    steps:
      - id: skip_check
        uses: fkirc/skip-duplicate-actions@master
        with:
          cancel_others: 'false'
          concurrent_skipping: 'newer_runs' # <-- a value that makes concurrent skip functionality works only if newer runs exist
      - if: ${{ steps.skip_check.outputs.should_skip != 'true' }}
        run: |
          echo "Run long test suit" & sleep 60

To be honest, I am not entirely sure how to solve it because I never combined those two features together. If you look at the checks in https://github.com/fkirc/skip-duplicate-actions/blob/b68a254ac00b33f707866bae1ebe647e56363d1a/src/index.ts#L144, you might figure out a solution.

If you are using the same_contentoption, then you might need to add the option do_not_skip: ["push", "workflow_dispatch", "schedule"] or something similar. Otherwise, it might happen that both PR and PUSH are skipped.
