A Unity ID allows you to buy and/or subscribe to Unity products and services, shop in the Asset Store and participate in the Unity community.

I simply reverted back to 2018/2019 versions. In the 2020 version there isn't the asset store anymore, just the web version. Hope they'll fix it...
Now there isn't a the asset store inside Unity. How can we manage to get the URI from the button working ?
