Question:
FIWARE IoT Agent Framework: How to define a device with nested attributes in IoT Agent e.g geo:json?

Description:
I can't find how to define a device where its entity contains nested attributes.
The need is to pass gps coordinates from a device to an entity having geo:json (like urn:ngsi-ld:Shelf:unit001 in tutorial https://github.com/FIWARE/tutorials.Entity-Relationships)
Following the https://fiware-tutorials.readthedocs.io/en/latest/iot-over-mqtt/index.html the below

curl -iX POST \
'http://localhost:4041/iot/devices' \
...
-d '{
"devices": [
{
"device_id": "motion001",
"entity_name": "urn:ngsi-ld:Motion:001",

],
"static_attributes": [
...

creates the count attribute

{
"id": "Motion:001",
"type": "Motion",
"TimeInstant": {
"type": "DateTime",
"value": "2020-04-04T07:52:29.00Z",
"metadata": {}
},
...
"count": {
"type": "Integer",
"value": "12",
"metadata": {
"TimeInstant":

}
},

How to replace the count above in order to get the below outcome ?

"type": "geo:json",
"value":

,

In all examples and documentation the attributes are defined in one level (not nested) https://iotagent-node-lib.readthedocs.io/en/latest/api/index.html.
