Gran Sabio

Hi, I'm new to using UNA, the thing is that I saw the UNA Team video of "Group Feed" and I saw that for Post and things like that they use Timeline, I tried to do this (also to show Posts and Discussions in the Timeline format, I think that's what they use here) but I didn't find any results, only for the Timeline "Updates", I want to know how I can integrate Posts and Discussions to the Timeline Feed format.
