How to vectorize an icon with background/shadows, with different colors, in the inkscape editor?

Question

Icons

I know how to convert regular icons to vector using inkscape (outline>vectorize rast, grayscale, scan 2, remove background, remove stack). Not strong in the program. And that's all I use it for, converting icons to vector and creating a font icon pack. Note, I don’t know how to correctly translate these types of icons into a vector, if you do as I described above, then the background color (the one inside the heart and disappears in the sleeve of the arm)
