How to make Signature work on closed screen

UFT One 24.2

SAP Fiori app - SAP NetWeaver - Release 800 - Version: 8000.1.2.1161

Chrome - Version 127.0.6533.73 (Official Build) (64-bit)

I am working on an application that requires a signature as part of the steps

I have been able to get this working and happy that it is signed and the script continues

BUT....

It needs the screen to be open to work.

I have got this working via call to 

Which is an analog recording
Window("Signature Analog Recording").RunAnalog "Track12"

I am attempting to see if I can stop the screen from 'going to sleep'

But wondering is there another way to get a signature onto the application??
