Change shared network location accessible by all replicas on aoag

I want to change the shared network location accessible by all replicas I first set up in an aoag. A new server has been stood up specifically to act as a file share witness and now I have to change the existing share network location to point to directories I have created and shared on the new server. I've updated it on the server cluster through theconfigure cluster quorum settings wizard, but not sure where to do it on sql server aoag. Is that something that updates itself automatically or do I need to go somewhere in the aoag and manually update?
