How to activate scanner in SAP ITS with EB ?


What is the simplest way to activate the scanner function of my MC33 when browsing SAP ITS with Enterprise Browser ?

I have downloaded the "Scanner demo App" on my MC33, and the scanner is activated just fine :

But I don't seem to be able to activate it through the config.xml DOM injection as described here :

SAP ITSmobile Usage Guide - Zebra Technologies TechDocs

Any help on that topic ?

Thanks & best regards
