External Trackpad recognized as Mouse instead of Touchpad

I have just purchased an external trackpad/touchpad and successfully paired it via Bluetooth. The problem is that there's no pointer; it only has scrolling and dragging functionalities. I have also paired it with an Android smartphone, and there the pointer is present.
I ran sudo libinput list-devices and in the Capabilities section, it shows only "touch" and "pointer" is missing. In the bluetooth setting, the touchpad is listed as “mouse, that's why it doesn't have the pointer capabilities.
Maybe I need to modify the udev rules?
