Setting up an email distribution list for Gmail

I gave my old Z10 to a friend who has exclusively used Android for years. She's a manager at a large business and she needs to send emails to groups of people. With the Gmail app on Android those lists appeared automatically once she created them, but so far she hasn't been able to get it working on the Z10. I've never had to do what she's doing so I'm at a bit of a loss. It's a business phone though... I'm sure it's something simple. Anyone know how to fix this?

There are several Gmail apps for Blackberry 10 but I have no idea if they work the same as the Android ones.
