I am so very confused. How does a person install an app in Nextcloud?
When I am signed into my Nextcloud site as the administrator, and click on “+ Apps”, I get a list of my installed apps, but I don’t see any categories showing that I am connected to an app store. If I click on the three line “hamburger menu” on the top left side of the apps window, the list shifts to the right only to reveal just a white area to the left with no text in it.
Last question: From the web site for the app store I downloaded the tar.gz file for an app, but I hesitate to decompress it, because I don’t know the correct way to install such a file. Where do I find instructions for the tar.gz files?
