Hi Julia,
In Microsoft Planner, we can assign a task up to 11 members. When assigning members, in the drop-down list, we see the name of the group members only.
Reference: Assign people to tasks
The integration of Project with Microsoft Planner lets you connect Project tasks to a Planner plan and track detailed work in Planner.
For detail information, please see Introducing new ways to work in Microsoft Project and Microsoft Planner: Linking Plans to a Project task
Thanks,
Neha
