Swagger API having different response with the change of Optional Parameters - api

Question

I am trying to create the OAS Swagger documentation for an existing API where the response for the API is changing on the basis of Query parameter. I am struggling to document this in a developer friendly way, so need some assistance. Below is the complete scenario for your reference.
EndPoint 1 : /order?expand=false
/order?expand=false
{
"orderNo": "12345",
"orderDetail": "Description of Order",
"orderMarket": {
"id": "UK"
},
"brandOrderStatus": {
"id": "LLA"
}
}
Endpoint 2 : /order?expand=true
{
"orderNo": "12345",
"orderDetail": "Description of Order",
"orderMarket": {
"id": "UK",
"descr": "United Kingdom",
"lang": "en-GB"
},
"brandOrderStatus": {
"id": "LLA",
"descr": "Some Status Description",
"lang": "en-GB"
}
}
Endpoint 3 : /order?expand=true&include=feature
{
"orderNo": "12345",
"orderDetail": "Description of Order",
"orderMarket": {
"id": "UK",
"descr": "United Kingdom",
"lang": "en-GB"
},
"brandOrderStatus": {
"id": "LLA",
"descr": "Some Status Description",
"lang": "en-GB"
}
"_embedded": {
"features": [
{
"id": "AJS",
"type": "FeatureType",
"descr": "FeatureDescription",
"prices": [
{
"type": "msrpNetPrice",
"amount": 0.00,
"currency": "GBP"
}
],
"group": "null"
}
]
}
}
I tried using OneOf, but don't really think that will work in this case as the structure is changing with every optional parameter.
Any thoughts as how this can be documented in Swagger documentation ? Or any other idea to get this documented.
