Configuring Chrome on Win10 to start up at a specific Zoom level

Hey guys.
Not exactly a lovelace question but it is frontend

I have an old Win10 Point Of Sale tablet I want to use and its resolution is 1024x768

Does anyone know how to create a desktop shortcut with command line options for chrome to open with a specific zoom level?

I created a dashboard that looks great but i did it on a 1920 resolution monitor (my desktop) and actually looks usable on this 1024 screen, but only with chrome zoomed in to 75%

Ive looked online but cant find any command lines that actually work.
Ive tried --force-device-scale-factor=1.5 but doesnt seem to work on newer versions of chrome
