Create a data browsing widget that searches ArcGIS Online, Living Atlas, and ArcGIS Enterprise.

[RyanWaller]

Much like this question that was posted in 2022. My organization would like to be able to browse/add data layers from the Living Atlas, ArcGIS Online, and internally to our ArcGIS Enterprise with a widget that is native to the SDK. The widget will work similarly to the search capability in place on Enterprise and AGOL with all appropriate filtering and sorting capabilities found in those tools' map viewers.

We are also interested in this. We'd like to add something like the "add data" widget from experience builder to our custom js api app.  I think the first stepping stone is something like this sample (https://developers.arcgis.com/javascript/latest/sample-code/identity-oauth-basic/) but instead of running a query of the items that belong to the logged in user, query based on the user search input, and would that query also peruse living atlas and general AGOL public data?
