How do I view WordPress on X server on corp.example.com with CloudFlare as my name server after obtaining example.com in the moomoo domain?

Currently, I run a service at https://example.com.
Then, I would like to view my company's HP in https://corp.example.com.

• example.com is retrieved from the moomoo domain
• https://example.com servers are AWS (ELB)
• Set CloudFlare to name server
• The company's HP is WordPress and is located on an X server

What did you try?

In what configuration can I use https://corp.example.com to view my company's HP?
Or please let me know if there is anything impossible.
