Keybow press multiple keys?

Hi all,

I would like to make my keybow mini do something when all 3 keys are pressed. What is the correct syntax to address all 3 keys together? Can anyone help? I would like to do something like this, but this is not working.

function handle_minikey_00 AND handle_minikey_01 AND handle_minikey_02(pressed)
    if pressed then
keybow.clear_lights()
    end
end
