How can I copy the TXT record into the DNS configuration in portal azure?

My case like this :

My website is stored on the portal azure. So I need to copy the TXT record into the DNS configuration in the portal azure

How can I do it?

Update :

If I check DNS Zones in portal azure, it's like this :

Have a look at the documentation Verify your domain with a TXT record first. To verify domain ownership you should add TXT verification record generated by Google to DNS zone of your domain, then wait for a while and run check. To do it you should know which company provides you DNS service.

To solve your issue you should follow steps below:

1. Look for DNS servers configured for your domain (NS records):

• via online service whois.net (if domain data was disclosed);
• via online service dnschecker.org;
• via Linux CLI with command:

  dig NS YOUR_DOMAIN_NAME
  

2. Find which company provides you DNS service:

• it could be obvious from step 1;
• via online service whois.net (if DNS service provided by registrar);
• via online service RIPE DB after converting DNS server FQDN name to IP.

3. Add TXT record:

• in general it looks like this:

  Type: TXT
  Name/Host/Alias: @
  Value/Answer/Destination: google-site-verification=VERIFICATION_CODE_GENERATED_BY_GOOGLE
  Time to Live (TTL): 86400 or leave the default
  

• for Azure you should follow documentation section "Add a TXT record for verification" and replace MS=ms XXXXXXXX with google-site-verification=CODE_PROVIDED_BY_GOOGLE;
• for Cloudflare you should follow documentation.

UPDATE Accordingly to your update you use Cloudflare as a DNS service for your domain, because both DNS servers are related to Cloudflare: eric.ns.cloudflare.com and tess.ns.cloudflare.com. To add TXT record you should follow documentation. In addition, have a look at the instructions provided by Google.

UPDATE 2 In case you don't have access to your account at Cloudflare:

1. try to restore access to your account at Cloudflare;
2. collect information about services related to DNS and create DNS zone at Azure;
3. change DNS servers at the registrar side to switch from Cloudflare to Azure (double check if you use any CLoudflare services).
