[Enhancement]: No way of setting token_for when using ChatMessage.respond #521
Description
What actually happened?
In order to send a message using the User Access Token, the token_for value must be set in the PartialChatter.send_message call, but ChatMessage.respond does not set this or have a way to set this.
What did you expect to happen instead?
Perhaps add a flag to ChatMessage.respond to use the User Access Token of the Bot, assuming it exists.
Also, it may be helpful for the documentation to mention that the token_for parameter must be set in order to use the User Access Token and avoid authentication issues when sending messages in chat channels where the broadcaster has not given channel:bot scope.
Minimum reproducible example:
Steps to reproduce the problem
Subscribe to event_messages in a channel where you do not have "channel:bot" scope, attempt to respond to a message. You will get a 401 authentication error from the helix endpoint.
