Convenience function to create a new AccountChannelRequest object which will yield a Call channel, initially carrying both audio and video.
This is the same as AccountChannelRequest.audio_call, except that the channel will initially carry video as well as audio, and instead of using supports_audio_call you should test capabilities with supports_audio_video_call.
See the documentation of AccountChannelRequest.audio_call for details of how to set the target (contact, chatroom etc.) for the call.
