Hey! At this point it might make more sense to just roll out your custom business logic?
After a successful signup - you could navigate the user to your desired page and show him the “Needs email confirm” popup. Then in your database you save a boolean variable such as “hasConfirmedEmail” and check that value whenever the user tries to do something in your app. Meanwhile on successful signup by overriding the user plugin you also send a email to the user with an identifier and link that calls your api and updates the “hasConfirmedEmail” value.
Hope that helps!
