How to convert string to BSON

I want to convert a string to BSON Obj to perform mongodb aggregate operation. All the queries will be stored in somewhere and now we have to convert string to BSON operation and show the result.

Lets say

var str = `[{"$match":{"tenantId":"TenantOne"}},{"$group":{"_id":{"referralType":"$referralType"},"value":{"$sum":1}}}]`

I've to convert to 

var bsonobj = bson.A{
  bson.D{{
    Key: "$match", Value : bson.D{{
      Key : "tenantId" : Value: "TenantOne"
    }}
  }},
  bson.D{{
    Key: "$group", Value : bson.D{{
      Key : "_id" : Value: bson.D{{
        Key : "referralType" : Value: "$referralType"
      }},
      Key : "value" : Value: bson.D{{
        Key : "$sum" : Value: 1
      }}

    }}
  }}
}

I've tried Golang MongoDB-Driver - Bson Unmarshal! I'm not able to use it properly.

try this:

    var str = `[{"$match":{"tenantId":"TenantOne"}},{"$group":{"_id":{"referralType":"$referralType"},"value":{"$sum":1}}}]`
fmt.Println(str)
var bdoc interface{}
err := bson.UnmarshalExtJSON([]byte(str),true,&bdoc)
fmt.Println(bdoc)
fmt.Println(err)
