Share photos without having to log into icloud

I created a shared folder on iCloud and set it to allow access to anyone with the link, and only allow read-only access. However when I open the link in my browser it asks me to log into iCloud. I also tried clicking on the link from a Windows computer and the same thing happened.

Is there a way to have the folder set so that when someone clicks the link the folder of photos opens so the user can directly view/download them?

Thanks in advance for any suggestions!
