How to edit npc’s classic response dialogue using script

i got an npc where u can give him an apple using a dialogue choice, and i was wondering how to make it so he uses response dialogue to say " thanks ", tell me if i need to send server or local script or something. keep in mind this uses the dialogue object

Could you elaborate? I’m not sure why this would require a script.

You need to create custom gui for that, normal dialogue doesn’t have much options

ye i created a custom gui for this dialogue a few hours ago already
