Synaptics SMBus Touchpad is not working

[Sarang_22]

I have HP Laptop - 15-di0001tx and windows 10 64 bit version 21H2, my touchpad is not working and I can't see touchpad driver anywhere under mice and other pointing devices in device manager (even after enabling 'show hidden drivers' option).
It had Synaptics SMbus touchpad driver before but now its not showing anywhere and I am unable to find the correct driver, someone help me out please.
