About google domains

Hi, I bought a domain from Google last night. However, I used a new e-mail address. I don't remember the email address I used. I remember your password and domain.

I forgot the e-mail address where I got the domain because I got it from the incognito tab. Is there a way for me to find out this e-mail address?

The Google support team can help you solve the problem

Hello:
You can do this:
1. Visit the whois website, enter your domain name to search, and see if there is any information such as email address
2. Check the order information in the background management of the domain name
3. Ask Google to help you retrieve it
