The recommended approach is to visit the URL for the plugin's settings page, but appended with a special query parameter to disable the output of its JavaScript. The plugin's settings page would typically be at a URL like <code>https://example.com/wp-admin/options-general.php?page=add-admin-javascript%2Fadd-admin-javascript.php</code>. Append <code>&c2c-no-js=1</code> to that, so that the URL is <code>https://example.com/wp-admin/options-general.php?page=add-admin-javascript%2Fadd-admin-javascript.php&c2c-no-js=1</code> (obviously change example.com with the domain name for your site).
