Hi @fafsdafsafs / @kolina Could you please review/check this PR when you get a chance ?

Hi! Sorry for the late response, currently our integration tests are broken for not related reasons. After we fixed them, I'll review this PR.

Can you please rebase the PR to the latest main after I fixed integration tests in ee5b5d1.

I want to re-run them after my fix in your PR
