Cesium's canvas blocks DOM events

I am using Cesium with react and I am trying to implement a Context Menu.
In order to do so, I am using a very useful library:

the problem is that the context menu won’t show unless I set Cesium’s canvas
pointer-events:none CSS rule.
But if I do so , I block all of Cesium events.
Is there a way to make the context menu show without setting the canvas pointer-events to none?
