Hi Yar,
Formatting the links as you showed unfortunately did not work either (error message about video format). At least I was under the impression that deeplinks work on Quest when https is used.
Thanks to Facebook https is not possible for local servers on the Quest, but DeoVR supporting http deeplinks would solve that issue.
Are you saying deeplinks are not working with neither http or https? Then consider this a feature request for deeplinks on the Quest in general 😉
Best regards
