I want to share my website onto facebook and perform a function if the facebook share is success.

I have used Facebook Javascript SDK with display : 'popup'. The share functionality is working fine but opens my page in a new tab which is causing problem executing my function. The issue is only for mobile browser. It is working as expected in desktop

Here is my code:

FB.ui({
       display: 'popup',
       method:  'share',
       href: 'https://www.mywebsite.com/mypage',
       },
       function(response) {
                if (response != 'undefined' && response instanceof Array) {
                    loadAutoPopup_thanksfb();  
                } 
       });
});

I tried With display : 'iframe' method, but it did not solve my problem Please help in return to same page after facebook share for mobile browser
