Facebook Live Chat Not working

Hello i have added the plugin to my site, and properly configured it.
I am facing a some problems loading it, as it loads in my browser i configured it, but l tested the same thing in a new incognito tab but it doesnt appear out there, also i asked my friend to please check if it working for him or not and the answer i got is its not working.

Note: When i inspected the page i got and error saying “Refused to frame ‘https://www.facebook.com/’ because an ancestor violates the following Content Security Policy directive: “frame-ancestors https://www.facebook.com”.
(index):7374 crbug/1173575, non-JS module files deprecated.”

Need help solving this error with the facebook live chat
