Why can the Xiaomi 15 Ultra Photography Kit not wake the camera of the Xiaomi 15 Ultra?

The Xiaomi 15 Ultra Photography Kit is featured with a multifunctional camera grip and a professional-like operation. By connecting the Xiaomi 15 Ultra Photography Kit via a Type-C port, you can make the Xiaomi 15 Ultra a professional camera with lower operational latency and easily capture in-focus shots with just one hand.
When the Xiaomi 15 Ultra Photography Kit is not used for a long time, it will enter the low power-consumption mode to save the battery. It is recommended that you re-plug in the photography kit to restore the normal connection. Thank you for your understanding.
