Customize button on product page with fancy product designer

Hi,
I'm integrating fancy product designer in my opencart web portal but i need help to add a customization button on product page on which user click and the fancy product designer window opens with product design id and user can customize the item with the tool. Currently only Add To Cart button exist on product page and no option or button to customize the product.

Can anyone help me to do that.
Thanks in advance.

Hi Printhike,
Can you be more precise about what you want?
Maybe I can help.

Kind regards,
