Want to move an object from one documents array to another array in another collections document

Hello,

I have problem where I want to copy an object from an array in one document in a collection to the same array in a different document in another collection, so it would look like this below:

Collection → document → array → object[0] (want to copy this)

To

Different collection → document → same array → insert object

I would appreciate any help to do this using Mongo Shell.

Let me know if you need to any more information.

Thanks in advance,
