Thanks @inakihn, that explains it perfectly. So we couldn’t just embed some workflow modeler UI component in our existing app: instead, we’d run the Modeler app alongside it, and provide a link to it from our app in some way. Presumably we could also update the Modeler app’s styling to make it look like it’s still part of our app.
In terms of IDM: is there any documentation about how to plug in our own custom implementation of this component for the Modeler app to use? I can see a post here that discusses this, and says that to completely replace the IDM app is “more involved and it is not very pluggable”. So I presume this means “It’s doable, but not really documented much, and you’ll need to dive into the code and figure it out yourself”?
