@higuita Don't think your missing anything, many of the scopes are no longer available as they came from Ubuntu touch and stopped when support from them stopped. Check out uapp explorer and the open app store to see what is still available.
I lost alot of the scopes you mention when I moved my mx4 over to ubports a few weeks ago, but still have calls and message scopes on the nexus 5 which has been on ubports alot longer.
