A user logged-in to Auth0 using their Azure Active Directory account when using federated log out should be taken to a custom logout page with a query string parameter for a button click action on the logout page. Clicking the button should take them to that URL.
The current implementation uses the federated query string parameter, followed by a simplified returnTo without any query string parameters:
It performs the Auth0 logout and then hands it over to the Idp which finishes the process at location:
Auth0 documentation used to implement the federated logout:
Redirect Users with Alternative Logout (auth0.com)
Use the OIDC Endpoint to Log Users Out of Auth0
None of them helped produce the desired result. Thank you.
