Can't hide/remove useless "Join the airdrop"

I live in a wrong country and can't join this thing. Even phone number from a proven country doesn't help, looks like registration is closed. However that thing is still wasting my UI.

Start by locating the client UI entry point that renders the “Join the airdrop” element and determine which client platforms are affected. Done means the unusable element can be hidden or removed without affecting available registration flows, with the relevant UI checks passing.
