Displaying Shortcode ONLY on homepage

I’m using a plugin that’s supposed to only display on the homepage, but instead it’s showing on all pages with pagination too (categories, stores etc).

Is there anything I can paste into the theme functions to make sure the shortcode is only visible on the homepage only? Any specific theme tags?

I tried this bit it’s not working:

<?php
if( is_front_page() ) {
echo do_shortcode(‘[my shortcode]’);
}
?>

Thanks
