Teams Code site

The update to be able to join Teams with a code instead of a link initally said there'd be a site you could go to so you could enter the code & join without needing a Teams app. Something like https://www.microsoft.com/micosoft-teams/joinmeeting

I am unable to find the site they created 

The feature was

https://www.microsoft.com/fr-fr/microsoft-365/roadmap?filters=&searchterms=80668

However I can no longer find the specifications.

Any ideas?
