Learnpress and woocommerce change

Hello.
I have Learnpress plugin that has woocommerce integration.
Woocommerce upsell plugins are not working with the cursors but checkout is done in woocommerce.
Cursors/products are in the LearnPress plugin and not in the woocommerce products list as they all need to have an cursor based option. Add woocommerce product ID to cursor field - so it knows with product to upsell.

I need an option for each cursor that is made or exists:
- Upsell a woocommerce product in the checkout

Upsell product pricing option:
-Product is Free
-Product is with original price

How to add it to cart (in woocommerce checkout page) option:
-Product will be added automatically to cart with picture and price (free of full price)
-There will be a Question in checkout with product picture/price if you would like to add this to cart. - If yes then it will be added to checkout product list.
