I created a new item in ArcGIS Online and chose the "Web Mapping" option, since the "Other Application" option has no URL field, which I suspect is a bug. I entered the URL to a publicly shared Tableau dashboard, populated the metadata and saved with no issue. When I click on the new items URL, there is a warning that you are leaving ArcGIS Online, and then the web page opens. I would like to display a non-ESRI application (Tableau) on my department's Hub site, and when I attempt to add this new item created from a URL in Gallery or Iframe, the page does not load and I receive this message: "public.tableau.com refused to connect." If anyone has any information on a workaround or solution, please let me know.
