I'm creating an experience focused on a map widget. One of the map widget's Tools is Search, which creates a low-profile square search button in the corner of the map. I'd like to stick my own custom geocoder in this tool. I know you can use a custom geocoder using the dedicated Search widget, but that doesn't have the same low-profile appearance as the Search Tool, and it's not integrated into the map widget like the Search Tool is. How can I use my own geocoder rather than Esri's default one on the Search Tool?
