Assign task to non-group members in New Planner

Hi, I’m encountering an issue with assigning tasks to users outside the group in the new Planner or Project. When I try to assign a task to someone who is not a group member, I receive the following message:

"The person you are trying to assign is not a member of this group, and will not be able to see their assigned tasks until they are added. Would you like to continue assigning and add them to the group?"

The options presented are "Assign and add" and Just assign"

If I select "Just assign," the user doesn't receive the necessary permissions to access the task.

Am I missing something? In my view, being able to assign tasks to users outside the group without needing to add them first is essential for cross-organizational collaboration.

Does anyone have any suggestions or know if this feature will be supported in the future?
