I also have unedited JPEG+RAW files from a Fujifilm camera and can only use/see JPEGs. The Shortcut posted above doesn't work for me.
As far as I can tell, Apple have quietly downgraded RAW support in the past year or so (at least on my iPad Air) and I think this is behind the problem.
I'm pretty sure I used to be able to share a RAW file to Macbook using Airdrop. They have an option to send the original data in the share dialog, but this does nothing and will only send the JPEG. In fact, the only way I can actually access the RAW files (from iPad) is by syncing the photo roll to a Macbook using a cable, and then exporting from MacOS Photos, which is quite a lot of faff for our Apple wonder-technology.
