Publishing multidimensional raster using ArcGIS API for Python

[JustinTse]

I am wondering if anyone has done this before. I used the to_multidimensional_raster to create multidim raster from a raster collection. Now I would like to add this to ArcGIS online so that I can share it as a webmap. I am not quite sure how to do it so it could recognize it as a multidim raster. I saw some example raster layers and the layer type is labeled as Imagery Layer (multidimensional). What would be the best way to achieve this?
