Woocommerce | Plus Minus remove negative numbers (min_value)

I ask you for help please, I haven’t come out of it for hours.

I set the quantity selector on the Woocommerce shop page,
which automatically puts the item in the cart and / or removes it.

I have a big problem, when I am on zero and I press – the numbers go negative, I would make sure that it cannot go below zero.

Thanks so much!!
