I think that it is a matter of “intellectual Property” in the source. Even the compression techniques of images or file storage like jpeg, or gif have gone through the fights that you can sell the results but not the source without paying what can be huge amounts. Even when you have virtually identical fonts there needs to be a different name to avoid the possibility of legal charges. It gets really ridiculous but that doesn’t change things.
If you have the required font on your machine and can put it together in Inkscape or Affinity I would do that or have a note somewhere allowing you to use a “similar” font.
