This looks like an internal PR, is anyone working on this?

[abdullahwaheed]

@natabene yes @Mashal-m is part of @openedx/fed-bom and we are working on this PR. Once her credentials are created, we'll proceed further

[natabene]

@abdullahwaheed Great. Please note that @Mashal-m will need to be onboarded by the 2U HelpDesk, so she doesn't need to sign the CLA. Please work with 2U HelpDesk to expedite the process. Also, this PR will forever be flagged anyway, if original author is no longer working for 2U. So you can either just override and merge regardless, if you can. If not, @Mashal-m will need to re-open this work in a new PR under her name, once she has been onboarded by HelpDesk.
