Handbell notation

Can you be more specific? There are some symbols to be found in the Symbols palette (press "Z" to display), and that's pretty much everything defined in the SMuFL standard for music notation. Anything beyond that you'd need to create as a graphic. But do be sure to use the search bar in the Symbols palette, and check here if you still have trouble finding something - could be you just aren't looking under under the correct name.
