Slack side conversations within a ticket can be deleted by either the agent who initiated the side conversation or an administrator. This guide will provide a step-by-step process to accomplish this.
In a ticket, open the context panel and click the Side conversations icon. If you’re not using the Agent Workspace, click Side Conversations located in the upper-left corner of the ticket.
A list of side conversations related to the ticket will appear. Select the specific Slack side conversation you wish to delete. Note that you can only delete Slack side conversations; email side conversations cannot be deleted.
Click the options menu icon on the right side of the conversation, then select Delete message.
A confirmation message will pop up. Click Delete to confirm the deletion.
Note: Once deleted, the side conversation will be removed from both the ticket and from Slack. Any edits or deletions of messages on the Slack side will also be reflected in the side conversations on Zendesk.
