Thanks for your effort, @Net-IT-Jonathan.
To consider a PR, we first need an associated issue. Can you please link this to one you're trying to resolve?
Our team triages the issues first and that's how we decide whether we need/want a change or not. If so, then only we'd look into PRs associated to those issues.

And it looks like there was no response to a question we've asked. As the issue was closed we're going to close this PR too.
