[1.16.4] How to prevent hoppers/other similar item extractors from accessing my container

I know that it has something to do with getCapability function in the container class, but I am not sure what it should return for the hoppers to be unable to access it. I've seen a similar topic for 1.12, but how do I make it work with 1.16?

Could you please explain how do I do that? I have this:

@Override
public <T> LazyOptional<T> getCapability(@Nonnull Capability<T> cap, @Nonnull Direction side) {
    if(cap == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY)
    {
        return itemHandler.cast();
    }
    return super.getCapability(cap, side);
}

private IItemHandlerModifiable createHandler()
{
    return new InvWrapper(this);
}

@Override
public void remove() {
    super.remove();
    if(itemHandler != null)
    {
        itemHandler.invalidate();
    }
}

What should I do now? I tried to make the getCapability to return null, but it crashed.

(I'm sorry, I'm still a begginer)

No, do not implement ISidedInventory. This is a vanilla system that is replaced by the Forge capabilities system.

If I return the empty LazyOptional, hoppers still can steal items out of it. The same happens if I don't override it.

LazyOptional.empty is...empty

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.
