getcallbackvalue
Reads a Lua callback function stored in a callback property on an Instance. The first argument must be Instance object and the second argument must be a string property name. The instance reference must be valid. The property name is resolved with Roblox property metadata and must refer to a property whose type is LUA_CALLBACK. If the property descriptor is missing, the property is not LUA_CALLBACK, the callback field offset is missing, no callback is stored, the LiveLuaRef is missing, the callback belongs to a different Lua global state, or the referenced value is not a function, the function returns nil. It also checks the async callback field fallback when the first callback slot has no callback. The function does not update the property.
