Registration Date <> Server Side API

Greetings,

I have noticed that the registration date of every user of my app is visible on the adapty web dashboard. However, I cannot seem to locate a field in the Server Side API that would allow me to request the registration date from adapty. While I did find a birthday field, I am uncertain if it is relevant.

I would appreciate it if you could add this field to the API request since it is already available on the web and essential for customized flows.
