I used this post for this idea:https://community.esri.com/t5/arcgis-experience-builder-questions/widget-for-sentinel-2-date-filteri...
Including a widget for EB similar to the imagery instant app would be very helpful for the buildout of custom ESRI solutions for stakeholders. Currently the timeline widget does not support imagery layers that are time enabled. This functionality would bring EB closer to some of WAB's widgets and allow for more custom solutions creators can make.
