How can I make this simple script appear In the chatbar, but also the speaker?

Hello! I want to modify this script:

game:GetService("Chat"):Chat(script.Parent.Head,"I am dumb lol", Enum.ChatColor.White)

What the script does above basically forces someone to say something, the problem Is that the message only appears on the speaker, not In the chat bar, so I want to modify the script so It also appears by the speaker and the chatbar (Also the reason why Is because I want a somewhat realistic NPC Player that speaks, and when they speak, the message appears by the speaker and In chatbar)
