Count items on the list

[iluxaar]

Hello.
How to add information about number of records in the type of sheet?
Need to create new object type?
Can you describe it in the documentation?
For example:

{
"data": {
"products": [
{
"id": "14913913",
"cost": 20086
},
{
"id": "14948257",
"cost": 9150
}
],
"listInfo": {
"count": 2
}
}
}
