I have multiple web applications leveraging Google Tag Manager (GTM), today we use this for Google Analytics as well as implementing Application Monitoring (NewRelic) and our Customer Success Platform (Intercom). We use SSO across these sites and I'd like to be able to add in either a sidebar or a menu overlay (using GTM), to allow users to seamlessly (SSO providing the auth) switch between web applications. I'd like to avoid having to implement a menu in every single web application, hence the desire to leverage GTM.
Wanted to throw the question out and see if anyone had any ideas / solutions.
Thanks!
