AutoWear starting google assistant with shake

Hi,
I don't really use the AutoWear speech recognition as I don't have a lot of tasker actions I want to perform from my watch.
But I do use Google Assistant a lot and it would be great if I could start the assistant with the shake action. So i wouldn't need to say "okay google" nor long press the watches button.

Is there a way to do this? Assistant doesn't show up on "system apps".

Thank you in advance.

Hi,
thanks for your fast answer.
But there is no "Google Now" under system apps.

Huawei Watch
Moto Z, Android 7.1.1
AutoWear v 1.0.26

 

Shake does not work on a Asus Zenwatch 2 .

Any simple profile trigger by anywear also does not seem to work , tried running the voice command by using self note, command is successfully received by tasker (as the notifications suggest) but after that nothing happens .

Tried the basic examples and also running a simple task to notify / vibrate when test command is received but no go .
