In GNOME 3.32 the global app menu is still present but seems to be going away:

I'm not sure whether it's related to this or it's a bug, but ever since I upgraded to GNOME 3.32 (Fedora 30), I can't enter Peek preferences, because the item is no longer available in the global app menu:

I found out that I can disable global app menu in gnome-tweak-tool, and then Peek gets an extra icon that I can use:

But that's inconvenient, because I have to disable app menu for all applications.

Also, with a fresh user profile, I see an extra icon with Peek, same as in the screenshot above, even when I don't disable global app menu in tweak tool. I have no idea what's going on.

Can you please implement an in-application icon to show the preferences window? Thanks a lot.

Reported from Fedora 30 using the latest Peek from Flathub.
