How to get value of a Transform tracked in a Sequence from a MovieScene?

Hi devs,
can someone help in finding the FTransform values of a Transform Track in specific frames of a Sequence?
I’ve played with MovieScene a little bit, trying to get what I want, with no success.

Mainly I have doubts on the whole MovieScene API and I can’t wrap things up.
I suppose I should use UMovieScene3DTransformTrack to get what I want, but I really do not understand how to make it work.

Plus, I really have some doubts about the differences between a MovieScene Track and a MovieScene Section, can someone please elaborate on how the whole system works? Or maybe provide some link to a good explanation of it? A snippet of code to get what I want should help, but I really wish to grab the whole Sequence system.
Thanks for helping.
