On the docs there doesn't seem to be a parameter for the prompt part linke shown in the uno docs:

Uno.Helpers.ProtocolActivation.RegisterCustomScheme(
    "web+myscheme", 
    new System.Uri("http://localhost:55838/"), 
    "Can we handle web+myscheme links?"
);

When I tested it in Edge, there was just the standart-prompt, not the custom text. Should this parameter be removed ?
It seems that this is browser dependent and should be at least documented where it will show the prompt or not.
