Using a registry module results in `cannot detect a supported external module source` errors

I can’t tell what the module source docs are suggesting I use. They say:

Modules on the public Terraform Registry can be referenced using a registry source address of the form <NAMESPACE>/<NAME>/<PROVIDER> , with each module’s information page on the registry site including the exact address to use.

And that string is exactly what the registry page suggests I use.

Could you be more specific?
