Hello ,
Thank you for posting your question in the community and the feature is working on my end at this time. Maybe there was a server issue at the time you were trying, is it still not working and have you checked to make sure you have allowed the traffic from the following resources:

If the issue is still happening try a different network maybe the firewall is blocking it. You can also contact us to report a bug as we may be able to help: https://twinmotionhelp.epicgames.com/s/case-community-page
Kind regards,
