Unrecognized touchpad on ThinkBook14+ 2024

Touchpad is not responsive in SDDM and KDE. No touchpad is recogized in system setting.

The system:

OS: Arch Linux x86_64 
Host: 21LD ThinkBook 14 G6+ IMH 
Kernel: 6.7.4-arch1-1 
DE: Plasma 5.27.10 
WM: KWin 
CPU: Intel Ultra 7 155H (22) @ 4.400GHz 
GPU: Intel Arc Graphics] 
Memory: 4149MiB / 31700MiB 

Under the dual boot Windows I can find the hardware ID being "GXTP5100", with I2C HID driver provided by microsoft.

Relavant infomation from `udevadm info -t`
