The issue isn’t that the file is raw. The issue is caused because it is using a CUSTOM linear camera profile, and whoever is viewing will need to also have that custom camera profile, or that camera profile will need to be synced in some way to the Adobe Cloud.
If you export as a TIFF or JPEG, and then share those, it will work fine.
It will also work fine if the underlying camera profile is one of the universal, standard profiles, like ‘Adobe Color’, as you’ve discovered. But I wouldn’t recommend this because the standard profiles were not designed to be used for negative conversions, and will distort the resulting tones and colors and in your images.
