How to create data items from JSON file in zabbix?

Question

JSON

The server returns JSON like this:

{ "{#DATE}":"2021-01-01+00:01",
  "{#ITEM}": {
    "{#CLIENT}":"Вася",
    "{#MONEY}":"20"
  },
  "{#ITEM}": {
    "{#CLIENT}":"Петя",
    "{#MONEY}":"80"
  },
  "{#ITEM}": {
    "{#CLIENT}":"Маша",
    "{#MONEY}":"45"
  }
}

I can’t figure out how to create a data prototype so that data elements are created:

"Вася"
"Вася - 20"
"Петя"
"Петя - 80"
"Маша"
"Маша - 45"

There is a data element that this file receives:

I'm trying to create a data element:

But the elements are not created, in the last data only the contents of json-all

I asked Google, but apparently I don't understand something, or didn't take it into account. What else needs to be done to get this information?
