Two fingers tap in C++ WinUI 3 applications for touch monitor.

[Ajith-GS]

We are trying to implement a two-finger tap gesture for showing the context menu. The context menu appears in touch and hold by default in touch monitors. In order to create customized actions, how can we recognize and track multiple touch points? Or is there an event that can be used to identify multiple finger touches?
Any assistance is much valued.
Thank you.

Using the pointer pressed and released events, I can track the number of touch points. However, another issue arises: how can we differentiate between a hold and a tap? According to the MSDN documentation, there is a time threshold that distinguishes a hold from a tap, but the exact value of this threshold is not specified. Could anyone provide the value of this threshold or share any relevant documentation? Any help would be greatly appreciated.
