Any recommendation to implement analytics on chrome package app(desktop version). Do we need to use any SDK or can we use Adobe DTM/traditional method(s_code.js) on the page level to implement analytics.
Not completely sure if you mean an AEM package. If so - see this ATCE on AEM and Analytics: Scott's Digital Community: Spring Editons of Ask the AEM Community Experts
If you mean a non-AEM app - please post in the Analytics community.
