How to add a button to the cart that will remove 1 item?

Question

WooCommerce

Hello.
I think the essence of the question is clear.
I have an i-m on WooCommerce, I need to add a button / link (namely a button / link) to the cart, which will remove 1 unit of goods using ajax.
That is, for example: I have 5 units of 1 product, I click on the button and there are 4 of them.
