I want to add a custom button in the catalog above your generated slider in the products that have options.
Is there a custom hook or something?
More specifically i want to achieve this https://drive.google.com/file/d/1P_xuIyqUyawdRxV8BJ0auVeKcnBOfSjm/view
There is a custom button there as you see which counts the number of different images.
I can code myself, i am just asking if there hooks i can use?
Thank you
