How to apply coupon in cart?

Question

WooCommerce

Hello!
Dear programmers, please help me solve the problem.

It is necessary to automatically add a coupon in the cart, provided that there are products in the cart that have a certain field of the ACF plugin.

$field = get_field('field'); //значение только цифры

If, for example, there are three products in the cart, and only two have ACF fields ('field'), then apply the coupon only to those products that have a field ('field') and this field ('field') >= 1
