Issue with KDE Plasma 5 and Spotify

Hey everyone,

I'm facing an issue with KDE Plasma 5 on Debian 12. Whenever I skip a song on Spotify, the notification sound plays. I've come across suggestions in other forums to simply mute notifications, but I still want to receive notifications. Therefore, muting notifications is not an option for me.

I have disabled all Spotify notifications in the notification manager, yet I'm unsure how the sound still persists. I don't want to disable notification sounds in the Plasma Workspace, as mentioned earlier.

Any insights or solutions would be greatly appreciated. Thanks in advance!
