How to register display use API?

Hi
I’m an android developer, I’m developing an android app using xibo api, and I need to register a new display with cms using xibo’s api like Xibo player. But I didn’t find any api for device registration in the api documentation. Swagger UI (xibosignage.com)

It is not possible to register a display using the Xibo API - if you are developing a signage player which you want to act as a display, please see the creating a player section of our developer documentation.
