Want to hide add to cart buttons from showing in product catelog

I want to hide the add to cart buttons from showing in the shop/ product catalog of all the products. In other words, customers would have to visit the actual item page to add the item to their cart.

I tried adding the below line of CSS in the Customizer but it did not work. Plzz help! Thx.

button_product_type_external { display: none; }
