Combining shapes

Hi, I want to combine the two circles into a new shape. The only way I know is to “group” or “frame” them. How can I combine them as a new “shape” as it is shown in the above image?

Use boolean operations.

Thanks! Question solved. I just realized that when the shapes are grouped, the system will later generates the newly-shaped icon as shown in the image (my questions is a bit nitpicky)
