Create maps server with ArcGIS online free

[Unity_gis]

I created a map with ArcGIS online free trial to bring in to Unity. Can this be done or do I need ArcGIS pro? I cant seem to find a way to get assign a server url

You don't need Pro. What kind of layer are you trying to load?

[Unity_gis]

I made a simple map here:

https://gamedev1.maps.arcgis.com/apps/mapviewer/index.html?webmap=ff695aece33f4e5e8be60495b1acaa11

How might i go about pulling this in to Unity SDK, I cannot seem to find the option to make it a map service, rest api like the public examples. All of the instructions I find online to do so are for arcGIS pro desktop app. I am using arcGIS pro online free trial

Ultimately though I would like to host 2d,3d layers and lidar data
