How can I verify that I'm an owner of my space?

[Алексей Баранов]

I'm looking forward to use my space as a knowlidge source for Google generative AI . According to this page I have to verify that I'm an owner of my space 
https://cloud.google.com/generative-ai-app-builder/docs/domain-verification

According to the page which is provided by the google there are six approaches how I can perform this for a subdomain/url.

But if you read them you can't find any suitable approach for Confluence. All of them are easy to implement for an owned web site. 

So how can I pass google verification of my confluence space  ?

@Алексей Баранов I do not believe that you will be able to use any of those at this time.  I am also not aware of any plans to change that to allow you to claim ownership.  I do know that Atlassian is working to allow users to use their own domain in cloud, I believe you have to request this.  https://support.atlassian.com/organization-administration/docs/add-a-custom-domain/

@Алексей Баранов can you accept this answer to help others?

[Aleksei.Baranov]

yeah sure if you tell how to do this. I never did it before

@Aleksei.Baranov You will need to do the following:

1. Contact support and ask to be part of the early access program https://support.atlassian.com/contact/   Include the following link in the request -> https://support.atlassian.com/organization-administration/docs/add-a-custom-domain/
2. Once they grant access (If it is not already full) you will follow the directions here: https://support.atlassian.com/organization-administration/docs/add-a-custom-domain/ 

Before making the request please make sure you can do the following:

• You need to be an Organization admin.

• You’ll need to make changes to your DNS provider. You may need to work with your IT team or network administrator to do this.

• To help us keep your site secure and protect you from man-in-the-middle attacks, your custom domain must follow the pattern <subdomain>.<subdomain>.<domain>. For example https://customer.support.acme.com.

• We create a unique SSL certificate for each fully qualified domain name. You can’t bring your own certificate at this time.

• You’ll be able to add an optional redirect, if you want to be able to share a shorter URL with your team or customers. For example, https://help.acme.com. This URL will redirect to your custom domain.
