Show git diff with GITG on Fedora

I am using this tool https://wiki.gnome.org/Apps/Gitg/ as a git GUI.

In Ubuntu when I open the application inside a git project is shows the unstaged/unadded files in the top left and I can easily see the diff.

But in Fedora I caot see the modified files, in the left menu I just see the branches, remote branches and tags.

How can I see the diff with gitg in Fedora? or is there another better tool?
