Is there a way to trigger dialogue once? (And then "queue_free()" it?)

[DOOMSTS]

So. I wanted to use this addon/plugin for my fist project (Because it looked like a very easy and powerful tool), but I wanted to use it as a message pop-up, not a character-NPC-menu/dialogue thing.

I want player to see/read message once and then I want it to "queue_free()" itself, so that player don't trigger it again.
I searched for a way to do it, but failed.

Please help me to find the right place to look for info, or an alternative way to implement such a function (but please consider that I am a noob at this and I want to mass-reproduce this function).

Thank you in advance.

And thanks a lot to the developer for making this addon/plugin!

Well.
It was easier than I thought.

I just had to add "queue_free()" at the message node.
Here is a picture of sample code, if somebody have similar question in future...

I guess I am a little dumb. Lol.
