Thanks @JoyerJin, I am on the private resolver team and will re-record the tests for the PR

[jamesvoongms]

As mentioned in email, I have added the re-recorded tests in #29285

The PR above must also be released in the same version as this as we were previously using a preview branch and main is missing these changes
