I have receive a solution for this, I just install HIDDriver, then it will dispatchDigitizerStylusEvent: dispatchDigitizerStylusEvent(timestamp, stylusData);
Then I can get x, y coordinates from DragGesture.
But one more thing that is I also need get Width of touch to send to client app, that would be perfect.
But I also feel very satisfy with this, thank everyone.

I am going to use Comunicate between Client and App(https://developer.apple.com/documentation/driverkit/communicating_between_a_driverkit_extension_and_a_client_app) to send width of touch (Pen/Pencil). But I have one issue that is this plist not satisfy for user client connect (use IOServicePen):
<key>IOKitPersonalities</key>
<dict>
<key>HIDStylusDriver</key>
<dict>
<key>UserClientProperties</key>
<dict>
<key>IOUserClass</key>
<string>NullDriverUserClient</string>
<key>IOClass</key>
<string>IOUserUserClient</string>
</dict>
<key>CFBundleIdentifier</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>
<key>IOClass</key>
<string>AppleUserHIDEventService</string>
<key>IOProviderClass</key>
<string>IOHIDInterface</string>
<key>IOResourceMatch</key>
<string>IOKit</string>
<key>IOUserClass</key>
<string>HIDStylusDriver</string>
<key>IOUserServerName</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>
<key>ProductID</key>
<integer>AAAA</integer>
<key>VendorID</key>
<integer>BBBB</integer>
</dict>
</dict>
Question: How can I edit this plist to satisfy with IOServiceOpen, and also can use AppleUserHIDEventService?
NOTE: I am not request entitlement yet, I will request later for development also of distribution.
