You don’t download edge drivers from the hub. You download them to the hub. And the way that you do that is by following a link that the channel owner will give you. Once you do that, you will see a screen where you can first subscribe to the channel and then select the specific drivers that you want downloaded to your hub.
If the channel is open to anyone, the driver link will usually be in the first post of their author thread here.
If they are limiting subscriptions for whatever reason, they will send you the link privately.
The process is usually pretty quick, but it can take as much as 12 hours. See the edge FAQ that I already gave you for how to determine whether the driver has been downloaded yet.
