org.mongodb.scala.FindObservable.execute() method missing base on example code

I found another example reference code from here:

mongo-scala-driver/getting-started/quick-tour.md

collection.find(gt("i", 50)).printResults()

I tried to use the same scala example for my example program

collection.find(equal("_id", "ABC1234567890")).printResults()

and still got error:

error: value printResults is not a member of org.mongodb.scala.FindObservable[org.mongodb.scala.bson.Document]
collection.find(equal("_id", "ABC1234567890")).printResults()
                                               ^

Is there an actual Scala Mongo example that works out there with the current code base that is available in April 2022 that can achieve my simple objective?
