Hi @Sameedahmad, thanks for the post.

Before you can enable branch subdomains, you must enable branch deploys for your branch and successfully deploy your branch.

To add a new branch subdomain, go to your site settings under Domain management > Domains > Branch subdomains, and select New subdomain.

Make sure you have enabled branch subdomains.

For more information check the link below.

Let me know the outcome.
