Deploy not allowed for user

Hi, I’m using Open Suse Tumbleweed and I like to install or update things from Discover, but I can use the terminal to, if is needed. I keep receiving the same message:

Aborted due to failure (Flatpak system operation Deploy not allowed for user)

So, I need o solution also for Discover, but also a solution for updating and also installing from terminal.

Did you install via openSUSE Flathub Setup | Flathub ?
