You can delete a specific kudos or other Matter post in Slack and Microsoft Teams, for example to remove a test kudos or inappropriate information, or to clean up a channel before rolling Matter out to your organization. In Slack, only Workspace Owners and Admins can delete messages from MatterBot. In Microsoft Teams, a Teams admin first has to allow users to delete messages sent by bots, and then you delete the post from the message menu.
Who can use this: Workspace Owners and Admins on every plan. Works for Slack and Microsoft Teams workspaces; in Teams, the bot message permission must be turned on first.
For an overview of the whole feature, read the Kudos Guide. Related articles: Viewing kudos activity history and Kudos notifications permissions for Microsoft Teams.
Delete Matter posts and kudos in Slack
By default, any member can delete only their own messages, not messages from bots. Only Slack Workspace Owners and Admins can delete messages from MatterBot.
If you're not a Slack Workspace Owner or Admin, contact the appropriate person. You can find your Owners and Admins in your Slack Workspace settings.

Delete Matter posts and kudos in Microsoft Teams
By default, Microsoft Teams admins and owners don't have permission to delete channel posts sent by an application or bot like Matter. You can change this in your permission policies in the Teams Admin Center (Messaging Policies) so admins can delete posts from applications or bots like Matter.
Microsoft also has an official help article on allowing users to delete bot messages in Teams.
