Storing CalDAV credentials for Kontact

Hi. I have Kontact set up with my Nextcloud server to keep track of calenders, to-do lists, etc.

Unfortunately every time I start Kontact, it asks me for the user password to Nextcloud.

I have kwalletd6 running and there’s lots of stuff in there. Is there a way to get Kontact to use kwallet6 to store the Caldav password?
