@duynguyenhoang I've just invited you to have write access to this repository. I'm very grateful for the work you are doing on this. Thank you!

@duynguyenhoang do you know a good way to test this. I am facing issues where the conversations are not updating as well and hence not sure if the notifications are working or not.

@infinite-Joy9l I am able to receive new messages, Could you please try it again?

Seem the problem with receiving new messages only occur in some cases. I am going to check it as soon as possible.

Cool! For Linux, after your PR, we can be working with an integration with libnotify (for Windows I still have no idea, by the way). Thank you for your effort!
