The counterpart of the external API in the Jitsi Meet Web app uses the search URL param jwt to heuristically detect that the Web app is very likely embedded (as an iframe) and, consequently, needs to forcefully enable itself. It was looking at whether there was a JSON Web Token (JWT) but that logic got broken when the JWT support was rewritten because the check started happening before the search URL param jwt was parsed.
