The cabinet can operate on any domain or subdomain. If you have a main website, it's more convenient to place the cabinet on a subdomain of the same domain — this way the website and cabinet are perceived as a single space.
Example: website https://name.com → cabinet https://profile.name.com or https://cabinet.name.com.
After configuring the domain, enable HTTPS so the cabinet opens over a secure protocol. Activation typically takes 20–30 minutes.
