Send a message in chat quickly after clicking a button

This is resonably impractical as it’s resonably impractical to get oAuth tokens for a viewer using an extension.

An Extension would first need to get permission from the user via an external window to send messages to chat.

There isn’t one

TLDR: it’s not practical to do this.

Why build an Twitch extension to send chat messages. When a user can just chat instead of click a button?

Whats the use case?
