I want to get the site information of tk domain in python-whois

Question

I want to get the site information of gg domain in python-whois.However, it is not possible to obtain information about a domain in a particular TLD(e.g. example.tk for the tk domain).

import whois

res = whois.whois("example.tk")
print(res)

{
  "domain_name": null,
  "registrar": null,
  "whois_server": null,
  "referral_url": null,
  "updated_date": null,
  "creation_date": null,
  "expiration_date": null,
  "name_servers": null,
  "status": null,
  "emails": null,
  "dnssec": null,
  "name": null,
  "org": null,
  "address": null,
  "city": null,
  "state": null,
  "registrant_postal_code": null,
  "country": null
}

I tried specifying a whois.dot.tk server as an argument, but I got an error saying that such a host is unknown. If you know, please help me.
