I would like to replicate the functionality of the Document Library "Require content approval for submitted items?" except that I want someone to have to approve only NEW items and not MODIFIED items. It seems like I should be able to do this with a Flow (assuming that I am not missing something with setting it in the LIbrary's settings), but am not sure how I can have the document visible to only the approver until and unless it has been approved. Any help here?
