How to auto upload any files with Nextcloud android app?

I want to auto-upload some doc and music files from mobile to the Nextcloud server, but I can just set the picture and video folders as the auto-sync folder with the Nextcloud. Is there any way to set up auto-upload for other types of files?

I currently choose syncthing to auto-upload files.

In the Auto Upload screen, hit the Three dot menu in the top right corner Set up a custom folder Any folder you set-up with upload all files to Nextcloud. Please note, it will not do a 2-way sync. It’s only uploading to the server. The Icon on that configuration should be a folder this a star on it.

What exactly do you mean by auto upload screen?
