I have just added a Size Chart button to my product pages that opens a pop up (used these directions https://shopify.dev/tutorials/customize-theme-add-size-chart)
Right now, it sits next to the Add to cart button, but I would like it next to the size selection dropdown.
I attached a screenshot. Any help is appreciated!
