Start dialogue from another branch on the same scene

Hi! New dialogue tree extension is pretty awesome, but kinda complicated at first glance.
I figured out how to start dialogue at the beginning of the scene, it’s pretty easy. However, I need to have two dialogues (from two branches) in my scene.
Like, first dialogue is over, then five seconds waiting, and second dialogue should start. I can’t figure out how to make it work. For example, how to start timer after dialogue has ended.
How could I do that?
Thanks in advance
