BUG with checkbox Hide add to Calendar Links for not purchased meetings

Hello, I’ve noticed that when I activate the checkbox Hide add to Calendar links for not purchased meetings the page of Zoom Events give me a critical error.

In the error log’s Zoom Plugin I have seen nothing but in the apache error log I have this error:

PHP Fatal error: Uncaught Error: Call to undefined function Codemanas\ZoomPro\Frontend\wc_customer_bought_product() in /var/www/my-site/wp-content/plugins/vczapi-pro/includes/Frontend/iCal.php:170\nStack trace:\n#0 /var/www/my-site/wp-includes/class-wp-hook.php(324): Codemanas\ZoomPro\Frontend\iCal->add_to_calender_ics()\n#1 /var/www/my-site/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters()\n#2 /var/www/my-site/wp-includes/plugin.php(517): WP_Hook->do_action()\n#3 /var/www/my-site/wp-content/plugins/video-conferencing-with-zoom-api/templates/fragments/meeting-details.php(78): do_action()\n#4 /var/www/my-site/wp-includes/template.php(810): require_once(‘/var/www/legade…’)\n#5 /var/www/my-site/wp-content/plugins/video-conferencing-with-zoom-api/includes/helpers.php(411): load_template()\n#6 /var/www/my-site/wp-content/plugins/video-conferencing-with-zoom-api/includes/template-functions.php(81): vczapi_get_template()\n#7 /var/www/my-site/wp-includes/class-wp-hook.php(324) in /var/www/my-site/wp-content/plugins/vczapi-pro/includes/Frontend/iCal.php on line 170, referer: https://my-site.it/dashboard/e-learning/
