[Bug]: Existing NextCloud admin accounts require NextCloud account password

[LokeYourC3PH]

I cannot make the title too long, so let me explain:

I have setup Authentik to connect to NextCloud via OAuth2, thanks to this app (seriously, thank you, SAML for NextCloud is an absolute mess and they should be ashamed of what they provide there). However, I am facing a minor issue:

On the NextCloud instance, prior to setting up Authentik and OAuth2, there were already some users on it. Creating new users and migrating is a lot of work and will require stupendous amounts of time, and as such, attaching to the already existing user accounts made it a lot simpler (again, thanks for that as well). The problem occurs however when it pertains to Admin Accounts:

When I make Administrative changes to the system, NextCloud has a knack for asking for password confirmation upon making said changes after x amount of time has passed when the user had become inactive (but didn't logout). As such, when I log back into NextCloud maybe 30 minutes after having logged in the first time, and make Administrative changes (Users, User Groups, Shared Folders, whatever have you), I get prompted for the NextCloud's local user account password, but this should obviously not happen since I am logged in via OAuth2/OIDC (this app).

How would I go about fixing this?
