Help with making NPC have speech bubble

Guys, how can I make NPCs have speech bubble like this?

use

game:GetService("Chat"):Chat(workspace.Npc,"hi")

Thank you, is there a reason why this error occurs?

tbh idk why but you could instead put the npc head or its hrp instead of the model itself and make sure your npc has PrimaryPart as Hrp set up

You would have to use chat service and make the NPC say something.
