Nextcloud app doesn't open documents ("Can't open this document")

Hi,

I have Netxcloud 3.23.0 and Google Docs on my Android phone. When I tap a .docx file in Nextcloud I get ā€œCan’t open this document. This file isn’t available offline. Make file ā€˜available offline’ in the file’s options menuā€.

There is an options menu available next to the file (the three dots) but there is no ā€œmake available offlineā€, only ā€œAdd to favoritesā€, ā€œDetailā€, ā€œRenameā€, and so on. I can tap ā€œExportā€ there, go to the notifications, expand the Nextcloud notification, ā€œLocate folderā€, select ā€œFiles by Googleā€ and the document opens. That’s a kind of a hassle.

I would expect the document to open in ā€œGoogle Docsā€ as it has the .docx extension and .docx is linked with Google Docs by default.

Do I need to configure something for that to work?
