Issues login in with the desktop client when using SSO

So I’ve configured SAML and SSO for one of my Nextcloud instances but now I get the following problem:

When trying to log into my account with the desktop client, after entering the adress of the server, the client opens the SSO login screen, instead of the “normal” login screen.
I am able to log into my account using that particular screen, but what’s the way from there? I would be able to generate a app password using the window that I’m in, but from there…?

Same goes for the mobile app, the only difference being, that on mobile, after some time, there appears a button asking me if i want to go back to the “traditional” login screen. But not on the desktop.

So it seems like I’am unable to log into my account, right? Or is there any workaround for this?
