Creating a button with system.content.button in Forge

I want to add a button to all pages at the same place the edit button is. I got this working in Connect by adding the generalPages module and setting the location to “system.content.button”. But i can’t find how this would work in Forge.

The documentation says that the equivalent in Forge should be the confluence:contentAction but i can’t find how to configure it to be a button (if that’s even possible) on the page rather then creating a menu item in the more menu.

Is there a way to do this in Forge or should i just use Connect?
