Load script only when you need it

In code block when you are using script add to PHP tab:

<?php 
	wp_enqueue_script( 'magic-grid', '/wp-content/plugins/_NZP_Devs-Toolbox//node_modules/magic-grid/dist/magic-grid.min.js', '', '1.0.0', true );
?>	

You need to put path from /wp-content/ and not just plugins folder

PHP

JavaScript
