How to perform lead and lag in MongoDB

I am using STudio 3T and I have query like this:

select [Dashbo],lead([Dashbo]) over(order by [Entered Date])
from ATest_prevback;

This is giving me and error. How to perform this in MongoDB? Can someone give me an example?

Thanks, Adi

Starting from MongoDB v5.0+, it can be done by using $shift in $setWindowFields.

db.collection.aggregate([
  {
    "$setWindowFields": {
      "partitionBy": null,
      "sortBy": {
        "entered_date": 1
      },
      "output": {
        lag: {
          $shift: {
            output: "$Dashbo",
            by: -1,
            default: "Not available"
          }
        },
        lead: {
          $shift: {
            output: "$Dashbo",
            by: 1,
            default: "Not available"
          }
        }
      }
    }
  }
])

Here is the Mongo playground for your reference.
