WebDAV with iOS App

Hi nextcloud community!

I run NextCloud on a ubuntu system and everything works fine.
But I cannot access a WebDAV with a iOS app called DJ Player Pro
The manual tells me, that the app only supports Basic Authentication.
see DJ Player Manual
Is there a way to access the files with this kind of authentication?
Looking forward to your comments.

Do you think it would be possible to access NC from the app with an app password created?
