The original SVG contains multiple paths and colors. Please create a plain.svg icon that follows our SVG guidelines and use that new icon for the font version,

Great job with the SVG! There are just a few adjustments needed:

1. The SVG needs to be optimized. Please follow this tutorial for guidance.
2. Since the icon contains multiple paths and colors, it can't be used as the font version. Please create a plain.svg version with a single path and color.
