Attempting to access raw photos from Google Drive directly from Pixelmator Photo 'Locations' you see only greyed out badges. If you access Google Drive indirectly by going thru FileBrowser Biz, you can access the RAW files, select them, and return back to Pixelmator with the RAW file
Interestingly enough, if you press and hold the Pixelmator badge/icon at startup, you see the RAW images as thumbnails....(these are not in Photos)

Should mention using Pixelmator Photo beta on iPad 6th Gen, with iPadOS, 3rd public beta
