How to compare two URLs?

[rasben]

Thank you for a very cool action.

When i create a Pull Request, a testing site is created for it.
How do i compare this URL with the prod URL?
I have both URLs available, but I dont know how to tell your action/applitools how to treat two seperate domains as if they're the same

Essentially, i'd like it to be something like:

      - uses: colbyfayock/applitools-eyes-action@main
        with:
          APPLITOOLS_BATCH_ID: ${{ github.workflow }}-${{ github.ref }}
          APPLITOOLS_API_KEY: ${{secrets.APPLITOOLS_API_KEY}}
          batchName: PR ${{ github.event.pull_request.number }}
          baseUrl: ${{ (The Prod URL ) }}
      - uses: colbyfayock/applitools-eyes-action@main
        with:
          APPLITOOLS_BATCH_ID: ${{ github.workflow }}-${{ github.ref }}
          APPLITOOLS_API_KEY: ${{secrets.APPLITOOLS_API_KEY}}
          batchName: PR ${{ github.event.pull_request.number }}
          baseUrl: ${{ (The PR-test URL ) }}
