clicking on the notification doesn't work on all apps

[KarkanAlzwayed]

So far, I have noticed that when I get a notification from a native app, it opens when I click it, but it doesn't on others. Like slack for example or discord. Nothing happens when I click on the notification. I have tried to install kdeconnect (I know I know third party), and when the app gave a notification that a phone is trying to connect, nothing happens when I click it at all. Thank you
