Attempting to form an array from the elements within an array of child objects

I need assistance with extracting child objects from an array in Angular7. The array currently has a top level that I want to remove, leaving only the objects with properties. Any guidance on how to achieve this would be greatly appreciated.

{
    "toplevel": [
        {
            "SetName": "name1",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        },
        {
            "SetName": "name2",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        }
    ]
}

The desired output should look like this:

[
        {
            "SetName": "name1",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        },
        {
            "SetName": "name2",
            "description": "blah blah blah",
            "managingEntitySource": "blah blah blah",
            "effectiveDate": "01/01/9999",
            "terminationDate": "01/01/9999",
            "systemEffectiveDate": "01/01/9999",
            "systemTerminationDate": "01/01/9999",
            "comments": "blah blah blah",
            "lastProcessDate": "01/01/9999"
        }
    ]
