Returning response in Protocol AppActivation

[bjorn-malmo]

We have a WinUI 3 application that uses the system browser for an Oidc authentication flow. We have a custom uri scheme for activating the application once authentication is completed (Uri redirect). Everything is working as expected.

The question is if it is possible to return anything to the browser as a response to the URI activation? Now, when the OIDC flow is completed and the flow redirects to our application, the browser is left at the last step of the authentication process since it doesn't get any response from the called application.

If the redirect URI is something like http://localhost/... we can respond with some nice HTML stating that the authentication process has completed, but if the redirect URI is myapp://auth/complete, the browser just launches the application without displaying anything more.
