When you install Matter to a Slack channel, Matter automatically creates a Web App workspace that is connected to your Slack channel. Pending if you want to keep the channel, this will affect the proper way to delete/remove Matter.
Option 1: Delete Matter, And Delete Channel
Click "⌄" next to the desired Channel.
Go to the Settings tab.
Click Delete this channel.
Note: Only Workspace Owners/Admins can delete a channel (Slack Documentation).
Option 2: Delete Matter, But Keep Channel
Go to the Web App.
Go to Channel Settings > General.
Scroll to the bottom and click Delete Channel.
Note: This option will only be available to Channel Owners (who created the Matter workspace).
You'll receive an email with a link and brief instructions to delete the channel. Follow those instructions and Matter will be deleted.
