Can't find Smartsound (Sonicfire Pro) in Preimere elements 15

There are instructions for accessing Smartsound in the middle of page 229 of the pdf Premiere Elements version 15 user manual. It says to access it through the music panel, of which there is none, only an area to add music to a production. As far as I could tell, this section has no mention of Smartsound contained within it. I looked that the version 14 pdf manual and it appears that the section referring to Smartsound is the same as in the version 15 pdf.  I've noticed that several screen illustrations in the version 15 manual seem to reference the version 14 software instead, primarily because it shows the activity bar (?) running horizontally across the page instead of the same type of bar running vertically down the right side of the screen.  It initially appears that the version 15 manual didn't update all the changes included in the version 15 software.

I'm a new user so I may have missed something.

Is Smartsound still available in Premiere Elements 15 or did it get removed without without updating the manual? I've used Smartsound in the past with other software and liked it.

Thank you for your assistance with this question.
