How to turn off bluetooth in MATE?

In MATE bluetooth seems to be controlled with Bluetooth Adapters and Bluetooth Manager in the control center. However Bluetooth Adapters only allows to control visibility, but not to turn bluetooth off and Bluetooth Manager lists available services and manages connections.

I'm aware that I can turn off bluetooth with sudo systemctl stop bluetooth, but there has to be a way provided by the desktop.

I'm using Ubuntu 18.04.

Blueman has the blueman-applet tray icon, it is located inside
Indicator Applet Complete (mate-indicator-applet package) - see image

It changes

$ rfkill list all
1: hci0: Bluetooth Soft blocked: no Hard blocked: no

to

$ rfkill list all
1: hci0: Bluetooth Soft blocked: yes Hard blocked: no

and vise versa.
