Give the possibility to configure a custom domain name for a specific ArcGIS Web App on ArcGIS Online (Web AppBuilder, Instant Apps, Experience Builder, ....).
Today, a web app have must an url like this :
https://organization.mapx.arcgis.com/apps/webappviewer/index.html?id=8863dbfb99d04bfew9d894eda9b030e...
Ideally, give the possibilité to have https://mydomain.org for a specific content, without any redirection.
Today, the only possibility is a redirection, but it's not the best solution.
