@Airbnb support does not seem to be aware of the Denmark unique code connection to Skat and give me the canned "Airbnb register the Tax ID for taxes remitted purposes and it Host's duty to report to the local authorities" response.
If you are still looking for advice, you can also take a look at Local Host Clubs near you to connect with hosts, who might be able to help you with area-specific tax information.
I am also reaching out to our host from Denmark @Sandra856 if she has any advice on this kind of situation!
