Unable to run UniVPN Client

[PlatonB]

Describe the bug
UniVPN client is built only for Ubuntu, which makes impossible direct installation on OSTree-based distributions. I tried installing this program via Toolbox, but the shortcut was not created in Gnome Activities.

Steps how to reproduce the behaviour
Download UniVPN Client for Linux from https://www.leagsoft.com/doc/article/103197.html and unzip it. Try installing the program inside Ubuntu in Toolbox:

toolbox create -i quay.io/toolbx/ubuntu-toolbox:22.04

toolbox enter ubuntu-toolbox-22.04

sudo sh univpn-linux-64-10781.15.0.1208/univpn-linux-64-10781.15.0.1208.run
