Does the POCO X7 support Bluetooth HID?

The POCO X7 supports Bluetooth HID. 
Bluetooth HID (Human Interface Device) on a smartphone refers to the ability of the device to act as, or interact with, human interface devices over Bluetooth. HID devices are input devices like keyboards, mice, touchpads, and game controllers that allow you to interact with a computer or smartphone.
Bluetooth HID is designed to be low-latency, which is especially important for activities that require real-time interaction, like typing or gaming.
Compatibility is crucial, devices need to support the HID Bluetooth profile for them to work seamlessly. Most modern smartphones support this by default.
