Facebook messenger share from Web no longer works?

I have integrated Facebook messenger share on website that worked perfectly but stopped working for now.

I tried 2 different ways but neither of them works.

Method 1. (worked perfect recently)

window.open('fb-messenger://share?link=' + encodeURIComponent(link) + '&app_id=' + encodeURIComponent(app_id));

Method 2 - load Send Dialog URL using the Facebook SDK for JavaScript.

FB.ui({
  method: 'send',
  link: 'example.com',
});

Both methods have same result you can see picture here.

You can check Messenger share for Web(not for mobile devices, on mobile it works.) on these links:

1. https://elfsight.com/tutorials/embed-facebook-messenger-share-button-on-website/
2. https://sharethis.com/social-media-buttons/facebook-messenger-share-button/

Same result everywhere. Does it need some permission or something?
