one subdomain for use central

[webactor724]

Description

I want the domain to be on WordPress, for example, site.com is on WordPress and with a specific IP that is completely separate from the tenancy system, but I want to have a subdomain named app.site.com where I can join and create a tenant. But

But I have an idea. I want to define 2 domains, one in the central domains
app.site.com
site.com
My goal is to run the subdomains that I consider for tenants in the main subdomain, for example
vahid.site.com
But I have a problem

When I want to enter a tenant through the impresonate method, the address is like this

app.site.com/impersonate/xxxxxxxxx
And I get an error that app.site.com does not include a subdomain.

In fact, I am not allowed to execute a request as centeal domain, which is a subdomain

Why this should be added

The purpose of separating the introduction section of the project in the main domain and an app subdomain for platform management and other subdomains for tenants
