How to use rex timeline and duration ?

Hi.

I want to replace all the "wait" actions in my project, because when I activate/deactivate the in-game menu I am using timescale, and sometimes things go wrong when I resume from paused in the time while a "wait" action is running.

I have lots of events where I use "wait", I've added a screenshot with one of them.

I've downloaded this plugins made by rex but I don't quite understand how they work, I would like to know if I can use them in a single event with lots of actions, like the image I uploaded.

Thanks !
