Run a behavior tree (Dialogue Plugin)

Hello!

I am using this dialogue plugin at the moment: Dialogue System - Game Development - Unreal Engine Forums

I know it’s not the basic part of the UE4 but someone might know what’s the issue or used it before.

I just need to trigger a dialogue using blueprint, normally the dialogues are triggered by a button. I created something like this: Imgur: The magic of the Internet

But it just doesn’t work. I’d really appreciate help from anyone, who know this plugin or know how behavior trees are working and why this one just don’t activate.

Thank you!
