Chorus Action?

I usually update the item and monster pages of the wiki, not the pages like this, so I don't know the format for adding actions. There's a new action called Chorus that tells the player "You may join a Jam Session and sing with your party members." For me, it is between continent warp and the farming actions. Could someone please add it in? I'm not sure when I got it, but I think it's from party jam, and getting singing to a certain level(or perhaps getting Fantastic Chorus)?

It's already on the page under Jam Session.

Ah. I hadn't seen that yet. Thanks
