If you need to remove Answer Bot from a Slack channel, you will need to delete it. It's important to note that deleting Answer Bot from a channel removes it from that specific channel only and is an irreversible action.
In the Admin Center, click 'Apps and integrations' located in the sidebar, and then select 'Integrations > Integrations'.
Once in the 'Integrations' section, find the 'Slack' section and click 'View'.
Click 'Configure' under your company name.
In the new page that opens, find and click on the 'Answer Bot' tab.
Click on the options menu (three dots) next to the channel, and then click 'Delete'.
