When submitting an action and creating event on success of that action in workshop popup says “Applying edits…” and then customizable green message after set on action settings. Anyway we can have capability that both can be hidden?
Their is unfortunately no first-class way to hide the green action messages.
That said, you are able to change the text of the green message by editing your action configuration in ontology manager.
If you really need that popup to not show, you can the action in a slate application, and embed the slate application into your workshop app. This would accomplish what you are looking for, but it is fairly tedious to set up.
