How to log in to nextcloud using jwt-auth?

I want to use our internal OA system for single sign-on access to Nextcloud, and choose jwt-auth as the single sign-on tool.

There are different apps for external user authentication, also with SSO:

And a few others as well on the app store. Haven’t found a direct link to jwt-auth, not sure if that can be easily fitted with an existing solution. Check out a bit their repositories as well, perhaps there were already similar requests.

Thank you.
