Why can't I find my purchased domain in Shopify settings?

Hello! I bought 2 domains from Shopify. One of them is mazonni.com. I received a confirmation email from Shopify and PayPal, but I can’t find my domain on the settings page. Three days have already passed.

I urgently need access to my domain.

I received confirmation from Shopify and PayPal in my email, everything is fine. I bought a domain 4 days ago.

How can I contact support?
