Outline supports mentioning a number of different entities including users and groups in your workspace using the @ syntax.

Users and groups

To mention another user or group directly you can use the @ syntax which will bring up a list of team members, keep typing to filter the list. Mentioning a team member or group will cause them to receive a notification if they have access to the document.
