Chat doesnt load -> Violates Content Security

hi

so i install this plugin few days back.. when checking the site, it was working well. But it stopped working. So here is some details for this developers.

1) Chat loads when i am logged in wp-admin but if not logged in or incognito mode, chat doesnt work. https://home.topkidzfiji.com/

2) Lighthouse is reporting an issue with the chat script. Since its a 3rd parties script (not on your server but rather on fb server), we are getting issues with Content security policy.. See the link below
“Refused to frame ‘https://www.facebook.com/’ because an ancestor violates the following Content Security Policy directive: “frame-ancestors https://www.facebook.com”.”

3) Just fix this issue please. i can see many people have complained and yet FB is saying to clear the cache. to FB chat developers, get off your bum and do your own investigation.. You would have figured out the issue by now..

Thank You
