How do we redirect users from the GitHub app installation page if they already have an account?

To have users install my app, I use the following URL. If they are doing this the first time, it redirects them immediately upon completion<app name>/installations/new

But on subsequent authorisations, it opens a manage page that doesn’t redirect them. Am I missing something?

The OAuth page ( works far better. It redirects the user if they are already authenticated.

But I’m reluctant to show an OAuth page on the first try, since it displays the following page which spooks out our users. There seems to be no way to limit scope such that “Act on your behalf” isn’t displayed.
