wake up from sleep(Or how to launch any app in the start-activity node.)

[Y K]

Looking for a way to wake up from sleep. (Or how to launch any app in the start-activity node.)
I'm currently building a flow that uses a browser node to launch a print app with a URL and then print.
The print application is designed so that it cannot print during sleep.
I understand that the easiest way to deal with it is to set the device to never sleep.
I'm worried about leaving the monitor on all the time. (I'm an older person, so I worry about burn-in even though I know it's okay.)

Here's what I've tried and failed:
First, I created a task that wakes up from sleep with Tsker and installed it as an independent application with the tasker app factory.
(I also confirmed that I can wake up from sleep by starting the application with ADB in developer mode.)
I was trying to see if I could start this app from the start-activity node, but I didn't know how to start an arbitrary app.

For the time being, I am considering whether to set the terminal not to sleep, or to install Tasker and connect with network nodes.

If anyone knows how to wake up from sleep or how to start an app with start-activity, please let me know.
