UI5 - OPA5 tests - simulate "right click" or "long press" or "context menu"

I am beginning with OPA5 tests in UI5 and I created a context menu that is shown when a button, label or an image is right-clicked or if user holds it on touch screen.

Now I need to write an OPA5 test for this. I can perform left-click using new sap.ui.test.actions.Press() but I am not able to do right-click or long-press.

Can someone help, please?

I believe I would be able to write it in jQuery. And as UI5 is based on jQuery there should be a way but I do not know how to combine jQuery and UI5.
