I removed the version downloaded from the Ubuntu app center and
installed the flatpack 46.0 version, this icon doesn't work as expected
either (the fact remains that the app icon in the applications menu is
different from that of the toolbar )
but it's better than the settings icon

I reinstalled the operating system and the gnome calendar app, I was
able to pin it to the toolbar but when I click on the correct calendar
icon a new window opens with the settings icon
