SAML + MFA: manually trigger the single logout URL

[rookie]

In Passwordstate it is possible to use SAML + MFA, but without specifying the single logout URL (Administration -> System Settings -> authentication options). Therefore, users do not have to log in again with a second factor after logging out on inactivity or by pressing the logout button.
 
After logging out, users are redirected to the logout screen where they can log in again simply by pressing the "Log Back In" button. So far, so good. But for security reasons! (e.g. shared computer) it would be good if there was a way to manually trigger the single logout URL and thus end the user session on the ADFS.

 

One way to accomplish this would be by adding a second button on the logout screen, for example.

Some votes for this would be appreciated.
