After MFA completed; close Tab/Windows automatically

**Is your feature request related to a problem? Please describe.**
I'm in the middle of a Proof of concept for my company. I find it a bit annoying, that after an successful Login via External identity providers (EntraID in my case) with MFA that the windows keeps open.

**Describe the solution you'd like**
Ideally, the window closes and returns to the Defguard client.

**Describe alternatives you've considered**
If that’s not possible, I’d like to have a “Close Window” button, or a timer such as “after xx seconds, the window closes automatically.”
