Enhancement Request: Update SignIn with Mobile to Handle Query Parameters and Redirect to Mobile App

Issue Description:

Background:
Currently, our SignIn with Mobile functionality does not handle query parameters and does not provide a smooth transition to our mobile app. This issue aims to enhance this feature to make it more user-friendly and seamlessly redirect users to our mobile app while passing necessary query parameters.

Feature Request:

Handling Query Parameters:

Currently, our SignIn with Mobile process doesn't allow for the inclusion of query parameters. We should update the functionality to accept a query parameter named rds-mobile-app in the URL when initiating the sign-in process.
Redirect to Mobile App:

Once the user has successfully signed in, we want the system to automatically redirect the user to our mobile app.
Passing Query Parameters to Mobile App:

Additionally, we should ensure that any query parameters provided during the sign-in process are passed along to our mobile app. This will enable our app to provide a more personalized and seamless experience for the user.

Expected Behavior:

When a user clicks on the "SignIn with Mobile" option and is redirected to our authentication page, they should have the option to include query parameters in the URL, specifically rds-mobile-app.

After successful authentication, the user should be seamlessly redirected to our mobile app.

Any query parameters included during the sign-in process should be passed to our mobile app so that it can provide a tailored experience.

Start at the SignIn with Mobile authentication entry point and trace how the sign-in URL and successful-authentication redirect are handled. Verify the rds-mobile-app query parameter and its values through the flow; the work is done when successful sign-in redirects to the mobile app with the requested parameters preserved.
