Good afternoon Maria, thanks for your question!

In your extension.py is the RENDER_IN_NEW_WINDOW = False? If so, it should open the SSO in an overpanel while keeping the user on the current page (i.e., dashboard in your example). If you already have that set to False we may need to look at your code to see if there is something in your code causing it to behave differently. If not, it could be something worth looking into on our side.

I just checked on my side using a extension in a stack that is on version {{4.5.4.0}} of UUX, and it is behaving as I would expect it to. So I'm curious to see what might be causing the behavior you're seeing.

Thanks!
