Why can't I use the flash when turn on the camera's ultra-wide mode?

Problem phenomenon:

When the camera's Ultra-wide mode is turned on, the flash icon turns gray and is unable to use.

Problem causes:

Since the effective distance of the flash is about 1-3 meters and ultra-wide mode is generally used for medium and long-distance shooting. The flash cannot be used effectively so, the system design cannot use the flash when shooting in ultra-wide mode. This phenomenon is not abnormal, please rest assured.
