It seems that this PR is targeted against an incorrect branch since it has a parent PR on one of our codebases. Documentation that needs to be updated for an upcoming release should target the next branch. Please change the target branch of this PR to next and rebase if needed.

As you already stated, this is not part of this integration and should therefore not be documented here as such either.

Things like these can be put up in the community guides section on our community forums.

Thanks for being willing to contribute though 👍
