The Button shortcode generates custom buttons in style with the theme
You can change the shape of the buttons by customizing the border radius in Appearance > Customize.
The buttons can be regular (with a border and transparent background) or can be Primary buttons (will use the accent color from the Customizer).
You can add it to your page with WP Bakery Page Builder choosing the shortcode below
Once added to your row, edit its settings by clicking on the pencil icon.
