You need to activate a widget to be able to use it in a campaign.
Click on “Save” to keep any recent changes done in the editor. Once saved, you can leave the editor whenever you want and resume where you left off.
When your widgets are ready, you’ll need to click “Activate” to use them in your campaigns.
Unactivated widgets are considered unfinished and cannot be associated with a campaign. If your widget is already activated, the button indicates it.
