You can use the present output as input to the following pipeline and get the desired output (add this pipeline to your present aggregation):

[
        {
                "$addFields" : {
                        "feeds.author" : "$author"
                }
        },
        {
                "$replaceRoot" : {
                        "newRoot" : "$feeds"
                }
        }
]
