The figma integration currently appears to require logging into beta.diez.org, but I cannot find any sign up option anywhere. Is this feature not available yet?
There are a few places we need to update beta.diez.org => diez.org in our codebase & messaging. The beta site existed for our private beta. Thanks for bringing this to our attention.
For now, until we update the urls: you can just manually remove 'beta.';
