Hi Abdul Khader Shaik,

Thank you for the invite, I am sorry to inform you I will not be able to answer your question as I am not experienced in what you ask.

Thanks

Regards,

With an excuse dear, I am not experienced with your particular question, however you can keep on searching to find the desired results

Wish you good luck !

I will tell you what I think.

I don't think you can do it because only the user of the device chooses whether to make themselves invisible or not. I also think it is a hardware thing (so it is somehow protected by the device's OS).

Maybe you can know whether a user is invisible or not if you connected to them before and their device is shown in your "history".
