How to insert new Object element in array in MongoDB - arrays

Question

I have this Document so structured
Process: Object
Code: 1
Descr: "Analyze"
DocumentToCreate: Array
0: Object
1: Object
2: Object
3: Object
4: Object
5: Object
Type: Object
Code:"R3"
Desc:"CV"
Condition: Object
0: Object
KeyDoc: "is not null"
1: Object
ReasonInsertion.Code: "03"
2: Object
Raw.Id: "is not null"
3: Object
Product.FlagDelete: false
6: Object
7: Object
8: Object
In the Condition object in position 5(filtered by value of Type.Code "R3") I have to add a new element, to find the correct document I should filter the one with Process.Code = 1
How can I generate a script to perform this update?
UPDATE
This the data in the document
{
"_id": {
"$oid": "728b678c11f25b32b1f59d8b"
},
"Process": {

{
"Raw.Id": "04"
},
{
"ReasonInsertion.Code": "99"
}
]
},
{
"Type": {

"Condition": [
{

}
]
},

},
{

]
},
{

},
{

},
{

}
]
}
]
}
I have to add as mentioned above a new element into object "Condition" in:
"Type": {
"Code": "R3",
"Desc": "CV"
},
"Condition": [
{
"Key": "is not null"
},
{
"ReasonInsertion.Code": "00"
},
{
"Raw.Id": "is not null"
},
{
"Product.FlagDelete": false
}
]
