Or remove the relevant staff members from the `variants` array.
`INVALID_ARGUMENT (400)`	`IDENTICAL_CHOICES`	Identical choices `<choices>` aren't supported.	Make sure to remove identical choices from the request. Choices aren't case sensitive. For example, "Student" and "student" are considered to be the same choice.
