Gnome-encfs-manager not working?

My goal was to find a simple and secure way of encrypting folders ,apps etc.So I followed thisarticle to do it. After I was done , I tried to access the GUI of the app but it didn’t appear. The system monitor did detect it but that was it . So I used the terminal to start the app and got this response :

$ gnome-encfs-manager

Which build of fedora was the rpm for?

Which version of fedora are you running?

Might just be a matter of age.

I think 26.

I am running Fedora 35.

It must be the matter of age, I forgot it was old, my mistake.
