Here is an example of how it's done in Safari.
Some notes:
- It wouldn't surprise me if this feature was restricted to Safari only by Apple
- You seem to be only able to export the full page screenshot as a PDF file
- The Orion full page capture can still be edited in the Photos app. Admittedly Safari's method has its convenient parts but I greatly value Orion capturing the page as a JPEG file
