(Annoying) WORKAROUND. Note that you have to have system requirements that allow 'mirroring' your iPhone, i.e., the latest Mac OS and probably the latest iPhone iOs.
Ok, here goes:
1) Turn on iPhone bluetooth. Go to your Mac and click the iPhone Mirroring app. A virtual iPhone should appear on your desktop Mac. If it doesn't or if you see a funny message such as "Your iPhone is in Use" you may need to look up answers to help you with that. (If you see "Your iPhone is in Use," try locking your iPhone - the one in your hand, not the virtual one on your Mac.)
2) When you see a virtual iPhone on your Mac monitor,
a) go to Photos,
b) select some photos
c) then click the 'send' icon (the box with the up-arrow)
d) select AirDrop (yes, I know this doesn't make logical sense, do it anyway)
Result: note that your Mac desktop appears as an option under My Devices at the top of the following screen
e) click the icon representing your Mac desktop computer
Result: see a virtual 'popup' showing that your photos are being transferred to your Mac
f) when AirDrop Complete appears, click the Show in Finder button
Result: In my case I'm taken to Downloads and there are my photos in DNG format
-------------------
OPTIONAL, but handy. I have an existing Photoshop/Lightroom subscription, so the following ONLY works for people
with a Lightroom subscription -- though if you have another photo editing tool, that should also work.
1) Copy your downloaded photos from Downloads (or wherever they were put) into a Lightroom catalog folder
2) Open Lightroom and then the catalog/folder where you put the pictures
Result: Now you've got your photos and you can edit them with a very decent editing tool
