What service event is triggered after a new volume is loaded?

I am trying to trigger a command as soon as the volumes load into the cornerstone viewports. Does anyone know what event would trigger after the volumes load and on what service?

Hello and thank you for reaching out.

I suspect Events.VOLUME_VIEWPORT_NEW_VOLUME would do the trick. A listener can be added to the viewport element itself to listen for this event.

Hope this helps.
