[Support request] Use existing buttons on website to work with products from plugins

I am struggling with additional css to style the button in the way i want – some things just dont work like border radius or font size etc, it doesnt update the button styling when i add those properties, so i cant get the button to appear in the style i want.

How can i use the style i have made in the Elementor editor on a button with the products from the strip plugin?

thanks
