    {
  data: [
    {
      id: "373417498731610145",
      coll: thisCustomer,
      ts: Time("2023-08-18T16:52:07.870Z"),
      name: "Adam"
    },
    {
      id: "373417539205595169",
      coll: thisCustomer,
      ts: Time("2023-08-18T16:52:46.440Z"),
      name: "Betsy"
    }
  ]
}

  2. List the second set:

    thatCustomer.all()
    {
  data: [
    {
      id: "373417596170534945",
      coll: thatCustomer,
      ts: Time("2023-08-18T16:53:40.760Z"),

    },
    {
      id: "373417539205595169",
      coll: thisCustomer,
      ts: Time("2023-08-18T16:52:46.440Z"),
      name: "Betsy"
    },
    {
      id: "373417596170534945",

    {
      id: "373417628173074465",
      coll: thatCustomer,
