Embed private Figma prototype with access token

It would be great to be able to pass the API access token to an embed endpoint for allowing read-access to the prototype (with a valid access token). Is this on the Figma roadmap or have you considered building out something like this? This would allow me to share prototypes for research with testers who don’t have a Figma account to log in with.
