Hi @makseq,
Just following up as you suggested in the Slack channel. Could you please bump this PR to the relevant team?
Also, I ran into a merge conflict regarding the proxy config, where the version in main didn’t seem to work for me. Please see #6567, Any guidance there would be great.

Thanks! 🙏
