[BUG] Spotify notification buttons don't work about crylia-theme

[Crylia]

@Shorakie That might be a good idea. I also plan to open and or focus an application once you left click on it.

BTW the playerctl is noted in the new README.md here

I'm gonna throw this in here since it's gonna pop up as an issue at some point:
The notification buttons won't work when you skipped a song with your media control keys or in spotify directly while one notification is still active. Spotify basically overrides the old notification and thanks to that its broken. You can see that when the title has no color anymore and the timeout is not correct anymore.

after reading the source code i noticed i didn't have the playerctl package installed. installing the package fixed the issue.
however its nice to pause the timer of notification whenever the mouse is hovering it or intracting with actions
