    # the below IF structure checks:
    #  - PR repository must be the official Decidim repository ( decidim/decidim )
    #  - default branch (develop)
    #  - if the PR in discussion is already merged
    #  - and does not the `no-backport` label
    #  - AND
    #     - trigger event is a close ( like in merge )
    #     - OR
    #     - trigger event adding a label AND any of the labels in the PR is a `type: fix`
    # Checking if there is an existing backport PR falls in decidim-action-backporter responsibility
