Couple of tools to use for situations like this. Magnetic probe which is a rod on the end of which is a magnet. Just make sure to hold onto it tightly or use a lanyard.
Another is called a claw tool. Small stick with a plunger on one side and claws on the other. Poke into recess, press plunger and the claws open. Get it over the target and let go of plunger and claws close and grab it. Pull tool out carefully.
Third is a hemostat - small pliers-like surgical tool. They make a long one and call it a fish hook remover.
Fourth - putty or chewing gum on the end of a stick. Just be careful not to make it worse.
Fifth - vacuum with nozzle necked down. Stick a straw in the end and duct tape it to force all the air to go through the straw.
