People with owner or team maintainer permissions can remove team members from a team. This may be necessary if a person no longer needs access to a repository the team grants, or if a person is no longer focused on a team's projects.
In the top right corner of any page, click your profile photo, then click Your profile.

On the left side of your profile page, under "Organizations", click the icon for your organization.

Under your organization name, click Teams.

On the Teams tab, click the name of the team.

To the right of the name of the person you want to remove, click > Remove from team.
