What titles does chess.com recognize?

Hello everyone ,so chess.com recognizes all the titles you'd expect it to recognize like GM ,IM ,FM ,CM and so on. But I saw a recent clip of gothamchess playing against a NI which stands for National Instructor.

Does chess.com recognize all the  Arbiter and Trainer titles and if so do they get the same benefits (diamond membership) the other titled players have?

The site only recognizes OTB titles:

That's not true they also recognize NI (National Instructor) which is not on the list. Iwas wondering if they recognize other titles that are not on their list.

No, they don't. They recognize NM.

Of course, you if you have a link to that player's profile, it could be verified very quickly.

I couldn't find the player ,but he was in one of gotham's clips

That was apparently from an FIDE event that was being broadcast. Chess.com uses the FIDE database and on those and apparently shows that title (and probably some other non-OTB titles) when doing so. The site doesn't recognize anything but OTB titles on the site proper or for free diamond memberships.

Here is an example from the FIDE Online Olympiad from last year: https://www.chess.com/events/2021-fide-online-chess-olympiad-division-3-pool-d/01/Kamwendo_Precious-Florentiades_Michalis
