What's the diference between "Play anim montage" and "Montage Play"?

In my Character BP I can add Play Anim Montage, and has the “Start section name” input. But in the Animation BP there’s Montage Play available, which doesn’t have that option.

What’s the diference between firing the anim montage from MyCharacter BP and from the Animation BP?
Is there a way to acces of the montage inside the animation BP?

Thanks :slight_smile:
