Dispatch - Social Icons in Mobile Nav Menu

I've gotten my social icons nicely set up on desktop. Obviously these are hidden on mobile, but they should show in the nav menu. However, the nav menu is only showing Facebook and Twitter, whereas on desktop in the top right I have Facebook, Instagram, Youtube, and Spotify.

How can I modify which social icons/links appear in the nav menu on mobile so it can be the same as desktop?

Here's the mobile menu right now: https://imgur.com/6U2bTny

Thanks!
