Hi @SilinMykola,

Thank you for the contribution!

By looking at all the code modifications, the changes looks good to me. No manual testing is required for now. We will check the build results further, moving it to Extended Testing.

Thank you!

@SilinMykola yesterday, we did with the testing activity of this PR and moved it further but as you made some commits again thought to check with you, are you still working on this PR? Please let us know, accordingly we will move it to respective status.

[SilinMykola]

@engcom-Charlie Sorry for the confusion. The recent commits are rebase-only to keep the PR current; no code changes were introduced. I’m not making additional updates at this time and don’t plan to make further changes. Please proceed with the appropriate status and continue with QA/QE activities.
