--header 'Authorization: Bearer eyJBdXRoZW....' \
--header 'Cookie: nav_track=d-c7bqoDvKh23*6uusMHgHPjyCDVqt9CSidnHkPjr*AptXHUx6aMmEfDYNpsQqCPi-d'

}

--data '{
    "Properties": [
        "Attributes.*"
    ],
    "Entity": {
        "Attribute": [],
        "Id": 91297
    }
}'

Response:

{
    "EntitySpecifier": {
        "EntityType": "Location",
        "Id": 91297
    }
}

But when retrieving the asset details I found nothing changes!
