Need advice on how to follow up after final

Interviewing currently. Had one with a recruiter for the company, then the hiring manager, then the COO this past Monday. The COO told me at the beginning of the call that I was one of two. At the end he said I should probably hear something by Wednesday (he was interviewing the other person on Tuesday). I sent thank yous after every interview.

Question—- should I send something to the recruiter at this point? Or just too early? I didn’t know if I should send another type of thank you and I am the one you should pick blah blah blah.

Sorry I am just so nervous and scared. (Laid off few months ago)
