Implicit conversion from a 'TMap of TObjectPtr' into a 'TMap of raw ptr'

My class stores multidimensional data (multiple ComponentDataMaps in a CacheMap):

UPROPERTY()
TArray<TObjectPtr<UComponentDataMap>> CacheMap;

UCLASS()
class UComponentDataMap : public UObject
{
	GENERATED_BODY()

public:
	UPROPERTY()
	TEnumAsByte<EComponentClassUE> ComponentType;

	UPROPERTY()
	TMap<int64, TObjectPtr<UObject>> ComponentDataMap;
};

And I am working on a reflected function that should find and return a ComponentDataMap of this CacheMap:

UFUNCTION(BlueprintCallable)
TMap<int64, UObject*>& GetMap(EComponentClassUE componentspecifier)
{
	for (TObjectPtr<UComponentDataMap> entry : CacheMap) {
		if (entry->ComponentType == componentspecifier) {
			return entry->ComponentDataMap;
		}
	}
	return EmptyComponentCacheMap;
}

And the compiler complains about:

Error C2440 : 'return': cannot convert from 'TMap<int64,TObjectPtr<UObject>,FDefaultSetAllocator,TDefaultMapHashableKeyFuncs<InKeyType,InValueType,false>>' to 'TMap<int64,UObject*,FDefaultSetAllocator,TDefaultMapHashableKeyFuncs<InKeyType,InValueType,false>> &'
0>        with
0>        [
0>            InKeyType=int64,
0>            InValueType=TObjectPtr<UObject>
0>        ]
0>        and
0>        [
0>            InKeyType=int64,
0>            InValueType=UObject*
0>        ]

How am I supposed to deal with this? Shouldn’t there be any kind of auto-conversion available?

Use raw pointers instead of TObjectPtr inside containers
