I would like to include Trace Downstream in a set of mini-lessons I am creating for upper elementary and middle school students so would like to simplify the process. There used to be the ability to include Trace Downstream in an app using the deprecated App Builder but I cannot find anything that allows that in any of the new Instant Apps or Experience Builder. Thank you for any feedback you might have!
I just learned (from @Jianxia ) that Experience Builder will include a downstream trace tool as part of an analysis widget that will be introduced with the October update to ArcGIS Online.
