correct way: plastic weld it back together, then use a thin coat of bumper repair for final sanding.
If you don't have access to a plastic welder go to the local autobody supply store and get mesh for fiberglass and 2-part bumper repair material. Grind the inside of the bumper about 2 inches around the hole, then tape the hole closed on the outside of the bumper, using the mesh and repair material do your repairs from the back side of the bumper. Once this dries, pull off your tape and the hole will be filled, you still need to grind the outside of the bumper around the repair and apply a thin coat of repair material that you will sand to perfection.

wait wait, certain types of plastic need a adheshion promoter for any type of repair material to stick, polyurathene is yellow in color and that need no adheshion promoter , TPE/TPO.TEO/ PP all those need adheshion promoter
if it were me i would plastic weld the hole shut, lightly grinding both sides, welding the hole shut again takes allot of experience to do correctly
apply repair material to both sides, sounds easy looks easy but its not
