Using shortcode and buttons have no functionality

I toggled on “Support Accessibility toolbar as shortcode or widget” in the settings and added the controls within the footer template file with:
<?php echo do_shortcode(‘[wpa_toolbar]’); ?>

The buttons show as expected, but they do not do anything or than link to “#”.

If I toggle on “Add Accessibility toolbar with fontsize adjustment and contrast toggle”, then those buttons work fine. But it’s not in the desired location. Hence I’d like to be able to use the shortcode.

What am I doing wrong?
