Cannot invite student users to the Studio group using the Manager user.

Hellow, When I search for the email address of a Student as a Manager of a Studio group, 'No results found' is displayed.

Both the Manager and the Student belong to a subaccount.

When I can't find a Student by email address, how can I add a student to a group?

Has your user demo-aoyama-student01 clicked through from Canvas to Canvas Studio before? Canvas Studio is connected to Canvas via the LTI standard, and I believe Canvas Studio users are created just in time when someone launched Canvas Studio from the Canvas account.
To test whether you can find that user elsewhere in Canvas Studio, you might try sharing a video to them via the user sharing . How do I share media with a user in Canvas Studio?

Thank you for your reply.
Yes, Student users have clicked through from Canvas to Canvas Studio.
