Now, From FrontEnd Users Can Search any of the item from database using their unique _id , Like this:

db.collection.find({_id: "3" })
Which returns the following:
    "_id": "3",
    "data": "because it is pleasure",
    "title": "Tesla Model Y",
    "type": "Car"
Question Part:
Now, Including the above-returned document, I also want to return those documents which have it’s the matching type value.
My Questions means that;  if the user is finding any document with their particular _id. let’s suppose 3 then it should return the following:
Find the Item with their Unique _id and $group the type field Value
    "_id": "3",
    "title": "Tesla Model Y",
    "data": "because it is pleasure",
    "type": "Car"
    "_id": "6",
    "title": "Mustang",
    "data": "non numquam eius",
    "type": "Car"
    "_id": "7",
    "title": "BMW",
    "data": "Man of Culture",
    "type": "Car"
Is that possible to do? Is that possible to $group the document after finding By Id ?. I’ve tried many ways but none of them are useful. Any Suggestions Guys?
It is not the exact format that you which but it is a good start since you get:
	"_id" : "3",
	"title" : "Tesla Model Y",
	"data" : "because it is pleasure",
	"type" : "Car",
	"related" : [
			"_id" : "3",
			"title" : "Tesla Model Y",
			"data" : "because it is pleasure",
			"type" : "Car"
			"_id" : "6",
			"title" : "Mustang",
			"data" : "non numquam eius",
			"type" : "Car"
			"_id" : "7",
			"title" : "BMW",
			"data" : "Man of Culture",
			"type" : "Car"
You could $unwind the field related and make sure you remove _id:3.  But personally, I try to work with the data as-is rather than putting more work on the server.  It is as easy, if not more easy, to manipulate the result like above in the application rather than having a more complex pipeline.
