Sync setup throug Nextcloud android app

A lot of apps which sync with nextcloud, like nextcloud notes, nextcloud decks, openTasks and carnet, use a simple popup to connect to your nextcloud app. You don't have to paste URL and enter pw in every single app, the connection is handeled by the main Nextcloud app.
it would be conveniet if also joplin would provide a similar approach to sync with nextcloud.
