How to fix the error uploading the site to the host (via CPanel)?

Question

HTML

I bought a domain and a host together on the same resource. I uploaded my site to the host, unpacked it, and it seems to work, but when I go to the domain, the page was not found. The letter where I bought the domain and the host states that if I bought the domain in the same order as hosting, it will immediately use the necessary name servers. nothing further needs to be configured. But then why is the site not visible?
