Raise Volume on Music Player


I am setting up a Rule to turn the volume of my sonos speakers up when I ask Alexa to "Turn up the Music" and also one to turn down the music. So I noticed that RM has a Action to Set Mode, Control Music Player, Send HTTP request. When I select to Control Music Player and then select Raise Volume, it doesn't allow me to set by how much? So my question is how much does it raise the volume? And the same question for lowering the volume?


It raises or lowers it by 5.
