Unable to start app, lacking ROOT permissions

[TriMoon]

I just downloaded the AppImage from the release page, to test this app.
But it didn't even want to start...

user@kubuntu:~/Downloads$  wget https://github.com/h3poteto/whalebird-desktop/releases/download/v6.2.4/Whalebird-6.2.4-linux-x86_64.AppImage

As you can see it uses a random mount on each run, and demands the mount-point to be owned by ROOT.
This is only possible when we run the app as root, which is a NO-NO...

The same happened when i tried the deb package...
