This syntax seems more straightforward:

getEmployeeNotes(employeeId: string): Promise<EmployeeNote[]> {
    return prisma.employeeNote.findMany({
      where: {
        employeeId,
      },
    })
  },

I'm just not sure which is better performance-wise in terms of the number of queries created and the GraphQL n+1 problem which I don't understand yet but plan to read up on.
