Limit the number of gifts

Hi. When I create a rule, the gift block is not displayed on the product page. If I understand correctly, this is the normal operation of the plugin.

I as well as many people have a variable gift, that is, the buyer can choose the color of the gift. But he can’t choose a color on the product page before adding it to cart because this block is simply not there.

Let’s say I disable the rule and add a gift individually to each product. Now the block with the gift is displayed on the product page and the customer can choose the color of the gift. However, since the gift is attached to each item, it is added as many times as there are items in the cart.

So a customer will add 3 items and get 3 identical gifts, but there should be one gift. There is no way to adjust this.

I need to have a block on the product pages that shows the user that he can choose a gift. I also need to limit the number of gifts to 1, regardless of how many items the user has added to the cart. How can I solve this issue? I will be satisfied with any variant of the solution, either with the help of a rule or as something else. Thank you.
