Hi,
I looked around the forum and found some old posts by Keith, the way I found to make an embeddable widget is by making the whole page as the widget, so I want to make an embeddable thing like this:
Then I could make what is inside the popup as the embeddable widget and let external apps make their circular button and make their popup then add my widget inside the popup.
Since the posts I found are old, I am wondering if there are some new ways that enable me to make the whole thing (circular button + popup + what is inside the popup) all as the embeddable widget, so the external apps don’t need to make their own circular button and popup.
Maybe I lack some knowledge about the widgets embedding concept so any hint or keyword or tool mentioning is very appreciated
