MongoDB Compass missing aggregation options

[Niclas_T]

Hallo,
Does anyone know why the MongoDB Compass do not have the possibility to use the $objectToArray ($objectToArray (aggregation)) feature on his aggregation creating window. Does the MongoDB Compass not support all aggregation features?

The $objectToArray aggregation operator works fine in the Compass (I am using version 1.21.2). Note that it not an aggregation stage, it is an operator which is used within another stage, like $project.

For example using the input document of test collection: { obj: { str: "foo", num: 99 } }

The aggregation query:

db.test.aggregate( [ { $project: { obj_to_arr: { $objectToArray: "$obj" } } } ] )

The screenshot showing the same using Compass:
