Magento 2: How to add Additional Options in cart on “sales_quote_remove_item” event observer

Question

I want to add additional options to the next product on the sales_quote_remove_item event while removing the first product from a cart.

First Product, I have already added the first product to cart with additional options

Second Product with no additional options(Normal Add to cart).

While removing First Product with additional options, I want to check if First product has additional options or not

if Yes, First Product will be removed from the cart, I want to add additional options to the Second Product in the cart as shown in the below screenshot.

                }
            }
        }
    }
}

I've tried the above code but It's not working.

If anyone has a solution, please let me know.

I would recommend to use it at the quote level rather than Item level. Using that approach it will be easier to achieve that. Quote attribute is the better approach for ideas you can refer below.
