Exctract object ID from BSON object

[revit]

I would like to extract the Object ID from a BSON object. To be more specific given a bson object I would like to extract the objectID components
as described in https://docs.mongodb.com/v3.2/reference/method/ObjectId/:

• a 4-byte value representing the seconds since the Unix epoch,
• a 3-byte machine identifier,
• a 2-byte process id, and
• a 3-byte counter, starting with a random value.

I appropriate help with that,
Thanks
