There should be an stop button in the notification if no device is connected.
It could be a hidden one as "Send clipboard" and "Send files" button's(when a device is connected). And swiping Down should reveal the "Stop" button.
STEPS TO REPRODUCE
1. Open KDE connect app
2. Do whatever you want to do with you android phone
You will see a notification at the top saying "No Devices Connected"
It is good but I also want an option to Stop the application from running so that if I'm not on my PC and just using my phone so I would not be annoyed by it everytime I check my notifications, currently I would have to go to the app info everytime and force stop it manually.
