Innertune-like Notification Buttons

[HatoGreyrat]

Describe your suggested feature

I would like to have buttons similar to Innertune in the notifications part to add to the library or favorites, but I think Libretube does not have a library or favorites, so you could add them or you could create a button to add directly from the notifications what you are listening to a selected playlist

I personally don't think that we should add more buttons to the notification, see #6868
