WooCommerce only one product in cart for specific category

Hi there,

suppose I have 2 categories in my shop (category A and category B): when a product from category A is added to the shopping cart, no further product from category A and category B should be added. However, category B should be able to add as many products as the customer wants (except category A).

– Category A: Maximum one product of category A, nothing else
– Category B: No limit (but not B and A at the same time)

After some research I found the following hook, which generally only allows one product in the shopping cart. Can someone help me with that? Hook for a product:
