anyway i can have the _sum in this findMany()

const bookings = await db.booking.findMany({
  select: {
    courseId: true,
    totalPersons: true
  },
});

const sum = await db.booking.aggregate({
  _sum: {
    totalPersons: true,
  },
});

const bookings = await db.booking.findMany({
  select: {
    courseId: true,
    totalPersons: true
  },
});

const sum = await db.booking.aggregate({
  _sum: {
    totalPersons: true,
  },
});
