"the system status area" vs "the top bar"
The text in https://gitlab.gnome.org/GNOME/gnome-user-docs/-/blob/master/gnome-help/C/bluetooth-connect-device.page#L101-106 says the icon appears in "the system status area". And also "The Bluetooth icon on the top bar" for the image.
I don't see "status area" being used to describe this area other places so mabye it should be "top bar".
So maybe change:
<p>When one or more Bluetooth devices are connected, the Bluetooth icon appears in the system status area.</p>
<p>When one or more Bluetooth devices are connected, the Bluetooth icon appears on the top bar.</p>
