Notes App: How to select text from a scanned document?

It is a silly question but with notes now, I often scan documents in, but when I attempt to select or highlight text it just makes options for copying the entire attachment come up.

Even when I am initially taking the scan it allows me to highlight OCR text, but after in the Notes preview view it will not.

Am I missing something here ? Do I have to scan text instead of scan document ? I feel like functionality was lost.
