Keep the screen active

Hello everyone;

I’m new to programming with Thunkable X recently, having worked with App Inventor before! I switched to Thunkable, because I can also programing for IOs here.
My question to the Comunitiy:
How can I keep the screen active in Thunkable so that the phone does not switch to stand by mode?
With APP Inventor I could prevent this with a “Notifiler block”. I have attached the blocks :wink:

Notifiler

Does anyone have a solution for me?

Also I searched around in the search function and in the Comunitie, in the meantime there is already a solution how I can insert Extensions in Thunkable X Cross Version!
Or is there a way of the Thunkable Classic platform to import the developed apps into the cross platform?

Thank you already for your help
Michael
