Track Users Activities in the LMS

Hi I raised the following with the support - Case #03092674 and they replied that they don't have a proper guide on this and I should check this in the community. Can anyone provide any help on below mentioned case? Appreciate your help on this.

The recent storyline update enables tracking in LMS by using xAPI statement triggers in Storyline. We got the following case:
- We create a number of storyline files where each file has one scene with number of slides.
- We then create a number of Rise lessons where each lesson adds one storyline file only so if we have 10 lessons, then we will have 10 storyline files to be used in each lesson and so on.
Now we want to track users activities for the entire course. As our entire course is a collection of multiple storyline files, where we should add the xAPI Statement triggers?

explains project level considering if one storyline file has all the scenes in a single file which is not our case.
