Hey SuperTokens team 👋 is there a way to block thirdparty signups from a certain page? We only want to allow certain users to signup on our application. We do this just by not making our signup page publicly available (not a big issue if someone does find it). But new users go to the sign in page and press log in with the thirdparty button, it creates and account for them because the thirdparty endpoint is the same for signup and sign in
