How to hide the default button when using a shortcode?

If you are using a shortcode and the "Show Button On" option is enabled, two buttons will appear on the page. To hide the default button added by "Show Button On":

 1. Assign a unique ID to the custom button, for example:

[save_as_pdf_pdfcrowd button_id="btn-visible" button_text="Customized Save to PDF"]

2. Add a CSS rule to hide the default button:

.save-as-pdf-pdfcrowd-button-wrap:not(:has(#btn-visible)) {
    display: none !important;

This will ensure that only the custom button with the specified unique ID is visible.
