Is there a URL Parameter for 3d Viewer Bookmarks/slides?

[RossFindlayCOC]

I am building and Experience Builder app and would like to embed an Instant app that displays the bookmark. slides of my 3D WebScene.

The Experience Builder books only seem to work on 2d views, so the slides of my instant app are all I have to go to the perspective (underground) that I want my viewers to see.

Is there a URL Parameter I can pass to my embed to get me to slide # 5  like the WebScene Viewer supports?

P.S. not using SceneViewer URL parameter because mobile UI is not user friendly. IMO.

@RossFindlayCOC  there isn't currently a URL param that will go to an individual slide but it does support the viewpoint url params so you could use those to go to the same location as the slide? An easy way to determine the viewpoint url params would be to add the share widget to a 3D Viewer instant app along with the slides/bookmarks widget. You can use the bookmarks to navigate to the proper location then open the share tool and copy the link and it will have the proper viewpoint params appended. 

Here's an example app showing how this works: https://jsapi.maps.arcgis.com/apps/instant/3dviewer/index.html?appid=cd02e0f4351843f98c2d385d08ed0d3...

I also think it could be a good app enhancement to support navigating to a particular bookmark. I'll look at adding support in a future release.

Also have you tried the Scene Viewer with the url param that minimizes the UI? https://www.arcgis.com/home/webscene/viewer.html?webscene=12f2c243d6a346beaee9702d96c19e7c&ui=min#3
