Upload frontend does not allow switching user account

[nivemaham]

The upload UI should allow users to switch accounts when login in.
If I logout and press login again, there is no way I can enter a new username and password.

The login screen redirects to managementportal. Since the user is still logged in to managementportal, managementportal directly redirects back to the upload connector.

Is there an option when calling authorization_code flow, to force logout of MP as well? If so, a small link next to the login button could be added like “switch account”
