Hi,
Thanks again. I have sort of got a solution for now.
Using a bluetooth device to keep the phone unlocked using smart unlock. Then use the automate to recognise the text on the screen with "Place*" keyword.
Finally use App start to run the google assistant.
The flow is here:
@Henrik, there is currently a 5 seconds delay for app start for unknown reason (from the unlocked screen not the launcher screen)
I wonder is there a way to go into the launcher from the unlocked screen by "swiping up/bottom" and then I can use the home button to launch google assistant.
