Hey @leuedaniel and welcome to the userforums of Nextcloud.
You’re referring to a so-called 3rd party app… and thus you should put your request in the referring github issue-tracker
As you can see (by clicking) there’s already an open request for that. Which means there’s nothing we could do over here on the forum anymore. And so I’m gonna mark this thread solved…
I know it’s no good solution so far. 
Happy NC’ing though
