I'm working with the new map components https://developers.arcgis.com/javascript/latest/references/map-components/?path=/docs/welcome--do
Is there any documentation on how to create a custom component using the map component paradigm (I.e. what's required to make "MyNewComponent" below work)? The old way was pretty clear with view.ui.add(...). This is a little different:
<ArcGisMap itemId={itemId}>
<MyNewComponent position="top-left" />
</ArcGisMap>
Thanks!
