User can not remove the effects or send/returns on the audio groups by right-clicking on the channel strips.

To reproduce:
- Open attached project and launch "AudioMixerTest" scene
- Open the window for audio mixer asset "Ambience" and duck it
- Make sure that one of the audio groups has a send/return or effect on it
- Right-click on one of the effects via the control+click short cut
- Observe that nothing happens

Expected result: Using a mouse, user can right-click and Remove an effect. The same function should be available if user is not using a mouse.
