In my Capacitor app I am able to open a new window to facilitate a login (with Auth0). Upon successful login it opens a Custom URL Scheme (which is registered in the Capacitor app). It does prompt to say Open In "my_app"? in iOS, but selecting Open does send me back to the app.
I would like to do this same thing, but without opening a new browser window, and without the prompt. Essentially without leaving the app.
My attempt at this was to set up my allowNavigation settings in capacitor.config.json, so that my auth provider is opened in-app. This worked, but after a successful login it just hangs. It doesn't prompt to open in the app or anything.
What sort of callback URL would be used for an in-app browser capacitor app? Would a universal/custom URL scheme be needed?
