With out iosScheme no access to database but with not access to authentification?

[FloWachter]

I am defining in CapacitorConfig file the iosScheme: "app" like this which makes it posible that i can fetch all data from the database when i remove it, it can not load the data base. But when i try to authenticate i am getting this error in xcode: {"code":"auth/requests-from-referer-app://myApp.io-are-blocked.","customData":{},"name":"FirebaseError"}

I know that http and https is not allowed as a iosScheme but I am out of ideas what todo?
