To disconnect a connected app:
Click Apps in the sidebar.
Find the connected app.
Click Disconnect.
Confirm the disconnection.
Lymnus access to that app is revoked immediately. Any agents that use that app as an export destination will fail if triggered after disconnection — update those agents to use a different integration or remove the export step.
Disconnecting an app in Lymnus does not automatically revoke the OAuth permission in the third-party app itself. If you want to fully revoke access, also remove Lymnus from the connected apps settings in the relevant service (e.g. Google, Notion, or Slack).
