I don't believe there is any claim of authority for RCOM.  At least I was not involved in making claims that it is required and I do not see it as such.  In fact, I have argued in the past that studies run by Wikipedians won't gain much from the process[1]. However, I do recommend that academics -- especially those who do not otherwise engage with Wikipedians -- to work with an RCOM member to coordinate a review in order to ensure that you won't see massive push-back when you start recruiting on Wikipedia -- as studies tended to see when they were run before the process.
