I assume you can open the product section that you created. Inside the file, pressed “Ctrl” and “F” to open the search bar, then look for “product-form__item .” Next to it add this “hide-buttons.” Click SAVE. Please see image below for placement.
Then in the theme.css file under the Asset folder, add the code below.
.hide-buttons {
margin-top: 0 !important;
visibility: hidden !important;
height: 0 !important;
}
