Not showing method description when autocompletion

I'm currently working on angular 2 with WebStorm. I saw someone else is doing so with Visual Studio Code. The above picture is Visual Studio Code. As you can see, it shows method description when showing auto-completion options. I really want that feature since I'm new to AngularJS so that will help me a lot!

Unfortunately, WebStorm does not show descriptions likeVisual Studio Code. It just shows options. I believe there must be options to turn this feature on in WebStorm but I can't find it. 

Please anybody help me to find it out.

Thanks
