And if it’s a weak dog, it’s not a problem; it doesn't really want to bite anyway :) and yes, it needs to be taught in a way that raises its interest, which it wasn't born with.
BUT with strong dogs, which naturally have "steam coming out of their nostrils" when they see an opponent or prey, this approach will inevitably lead to conflict with the owner (the one who initially encouraged all of this and then started yanking, choking, and shocking).
Where does the redirection to the owner and the nipping come from, you ask? Well, you did it yourself with your clumsy little hands guided by a shrimp brain...
What to do?
TEACH PROPERLY
Do not let it come to conflict while maintaining a balance between the desire to bite and the ability to hear and listen to the owner.
Do this gradually, understanding where such an approach will lead.
It’s so simple.
