Limit users to seeing only Documents Created By themselves

Summary:

We are implementing a document class and would like to limit a certain group of users to only be able to see documents where created_by = their own user.

The user should be able to create new documents in the document class, but only view their own via manage documents.

I have attempted this via Item Class security and via adding the User to the 'Team' on the document. But this does not assist with still allowing the user to create documents.

Does anybody have any suggestion as to how this can be achieved?
