Is it possible to create a custom button in the overflow menu that opens URLs or mailto links or anything else? I know I can add custom links and buttons to pop ups, but I want to be able to add one outside a layer and feature. For example, I'd like a user to be able to view the overflow menu and below the existing options (under Share Map) there be a custom button than when clicked on opens a webpage to a url, say a survey123 url/app, or a mailto url that opens their email app with a preaddressed email to our helpdesk.
