how to export a multipage note as a pdf file

I scan a document. Today I finally got someone to show me how to crop the document scan on the iphone.

Not very convenient; it would be much better to be able to crop on the computer, where I could use a mouse/trackpad--which is more accurate--but so it goes.

After Airdropping the multipage note to my iMac, the remaining question is how to export the multipage note as a pdf from Notes on the iMac so as to save it as a multipage pdf file.

When I try to print the multipage note, the Notes app on the iMac decides there is only one page--the top page.

Not so useful.

The docs are not there as scanned pdfs. they were imported into Notes using Scan Document.

I.e., they are not there as Scanned PDF in Notes; the dropdown menu you show is not present.

there is NO file type listed--not pdf, not anything

there are, say, 20 notes.

if I select them all, then click on Export as PDF from the File dropdown menu at the upper left, only the first is exported to the pdf file.
