Controller method annotation to be able to call a controller's method before verifying two factor challenge for 2FA

Controller method annotation to be able to call a controller's method before verifying two factor challenge for 2FA: Is your feature request related to a problem? Please describe.
After logging in with with username and password, but before having verified the 2FA challenge, no API/Page controller method can be called by the page showing the 2FA challenge during TwoFactorChallengeController::showChallenge. All requests are redirected to "core.TwoFactorChallenge.selectChallenge". Meanwhile an anonymous user can call every controller method which is annotated with PublicPage.
