Implementation Reference
- The core handler function that executes the tool: resolves usernames to sys_ids, queries sys_user_grmember table for memberships, and deletes the records to remove members from the group.def remove_group_members( config: ServerConfig, auth_manager: AuthManager, params: RemoveGroupMembersParams, ) -> GroupResponse: """ Remove members from a group in ServiceNow.
