How to turn on speaker during VVM?

How do I turn on speaker while listening to Visual Voice Mail?

I currently do the following to listen to VM:

Phone App --> Calls --> VVM --> Down arrow for the call I want to listen to --> Play button

I can pause the playback and mute the playback, but can't find where to put it on speaker. I can put VM on speaker if I call regular VM and enter my password. I just can't seem to put VM on speaker when I listen from VVM.

Do you see a speaker symbol below the Down arrow? That's for speakerphone. When it's white, speaker is off. Press it, it goes blue and speaker is on.

You can even turn speaker on before you start playing the message. Not sure if that setting gets 'saved.'
