Hey @Emiel, your title is published, but as it's for sale as a game, it's only available in China currently. That's standard practice for most games on Viveport. You're also available in the Viveport Arcade program.
If you check out the Viveport Developer Console (where you uploaded the build, added marketing assets etc) it should be clear. If you have more questions, you can PM me or reach out to the content development team.
