Unable to create link in aero Geospatial

Hello i just get the access to test geospatial, i've made a quick test using adobe ressources and put a dinosaure in the street. Unfortunately aero is unable to generate a link. I tried the Export /Import solution but it doesn't work. i have a creative cloud personnal access and i work on desktop, so it's seems not to be limited by any admin permission.

I would love to have a solution on that, so i could test those super cool features 🙂

thanks !

Ben
