Mouse pointer not opening remote server application menus while using a real mouse on android.Where as hand gestures mouse works fine

I am connecting to vncserver using rvncviewer from an Android device. I use RNC viewer to access intellij installed on server from the android device.The mouse connected to my android works good I can click open any android app features using that.but when I try the same mouse in intellij in server in Linux connected through rncviewer the menus are not opening. I have to use finger gestures on Android screen to open intellij menus and to enable right. Both mouse pointers(hand gesture and real mouse pointer) look very different too. Using hand gestures is not a very comfortable option. Is there way to get the real mouse pointer work there on the server app..
