Subreddit for asking actual (credentialed?!) experts about Long Covid or ME/CFS?

I’m not sure if this even exists, but I’m looking for a sub where I can interact with actual experts on topics relating to Long Covid or ME/CFS. AskDocs doesn’t really seem appropriate, because I’m not necessarily looking for personal health advice, but rather an understanding of the pathology of these diseases and their potential impacts on different biological processes. The COVID longhaulers sub doesn’t seem like a great option either, as from what I’ve seen it just seems like there’s a lot of absolute nonsense in the comments there.
