How To Insert Snapchat Conversion Tracking Code In 4.7.2?

Dear members,

I am trying to add a Snapchat conversion tracking code to my site but I do not know where to add it, can someone please let me know about this?

I want to add it on all pages

Your comments as always will be highly appreciated

Look at how things ar done for Google and other sites. Simply use the hook to either add your script or to reference it from the js directory.
