Due to the following update for Atlassian Assist, the functionality to customize chat bot message has been disabled.

Upcoming changes to Atlassian Assist in Slack

Updated bot notifications

What is it? We heard your feedback that Assist notifications create noise for agents and requesters. Assist still adds a comment to the thread, and it will now also at-mention the requester or the assigned agent to subscribe them to thread notifications. This means all interactions happen in one place: on the request/issue thread.

As a part of this change, request participants will only receive request updates by email, unless they comment on the request thread in Slack.

Admins can no longer customize the bot messages sent by Assist. You can still turn these messages on or off as needed.

What should I do to prepare? If you have customized bot messages, we recommend saving a copy of the content in case you want to reference it in the future.

There are demands to have the function of customizing bot message.
