On Web interface context menu + share doesn't work


when using the web interface of Nextcloud and right-click a file or a folder + “Share file/folder” nothing happens.
Is this a bug - If yes I am surprised nobody mentioned it before me - or did I miss something?

Windows 10
Opera/Chrome/Firefox: Same issue
Version of web interface I don’t know (is there a way to get it?), provider is us.hostiso.cloud

There’s no web interface for Nextcloud.

Edit 1
Reading this image I see “Your Nextcloud administrator has the option to disable these features …”. I asked us.hostico.cloud if they disabled sharing options.

Edit 2
And yes, I got an answer and they disabled this feature. So take care before choosing your provider …
