I understand the desire, and I can understand why you feel it needed. Whether or not the pop-up is designed to be a confirmation of each command execution or a confirmation about granting access to a particular phone, I am not sure.
However, given that click2call does not seem to interact with the remote control settings at all, makes it a moot point at present. I am not saying that remote control and click2call should not interact with one another, but until they do, a pop-up of any type does not seem possible.
I will be back in the office today and will play with it to see if I can get any reaction from the remote control functionality. While I think it may be a bug, I am not really sure as the documentation is pretty light on the purpose of the pop-up and how the interaction is supposed to work.
