Current questions and answers regarding the map editor.

I already have a general idea based on the example of recruiting a hero, and I would like to delve a little deeper so that the hero not only joins but also says something, for example: "Because you freed me, I will do my best and be your ally in the war against the demons who ambushed and captured me."

"Because you freed me, I will do my best and be your ally in the war against the demons who ambushed and captured me."

How can I do this with a script?
I just want to be able to change the text.
Thank you in advance for your answer, Winner!!!!
