I'm practicing mongoDB with a small tweets dataset right now and don't have much experience with $graphLookup. For each document that matches, I'm trying to find the screen_name of the user the tweet is replying to, and if that tweet is also a retweet of another tweet, then display the user screen_name of that tweet too, so on and so forth up the hierarchy of retweets until the original tweet.
A standard document of retweets in the dataset looks like this

This is the query I have so far
db.tweets.aggregate([{$graphLookup:{from: "tweets", startWith: "$text", connectFromField:"text", connectToField:"retweeted_status.text", as:"Retweets Hierarchy"}}])
But this isn't really showing the screen_name, I'm not really even sure how to that while still matching the text to the fields and I'm so lost any help would be much appreciated.
My ideal result would be something like the image below, where it would show a clear structure from the bottom up.
