How to verify a domain for Yandex.Connect via WHOIS?

Question

Domain Name System

Good afternoon.
Please help me solve the problem of domain ownership verification.
The fact is that we don't have a website yet, and for this reason I can't confirm the domain using the Meta tag, HTML file, DNS record methods. Only WHOIS remains
The connection says what you need:
Add and confirm in https://passport.yandex.ru/passport?mode=changeemails the e-mail address specified in the WHOIS data.
The following fields are checked from WHOIS:
Email
Contact
Registrant Email
Admin Email
Tech Email
If you do a whois lookup, then the e-mail in the Yandex passport corresponds to Registrant Email, Admin Email, Tech Email.
The only thing I don't understand is Email, Contact. Where is it, can't find it?
When checking, Yandex writes "The corresponding email address was not found in the WHOIS data"

Answer 1

Free DNS can be used for the duration of the check or contact the domain registrar to change the whois data.
