The linked page (https://lookup.icann.org/en) seems to work only for .com domains?
"No registry RDAP server was identified for this domain. Attempting lookup using WHOIS service."
"Failed to perform lookup using WHOIS service: TLD_NOT_SUPPORTED."
Not just .com, it also works for .org, .app, .dev, etc.
As suggested by another comment, it looks like not all ccTLDs support RDAP. For example, .io does not.
