View our custom arcGIS map to the user using js SDK

Hello,
We have uploaded a new ArcGIS map to our account, the map appeared in the Wialon local system in the map list normally and it's ok.
Now I have to develop a custom app for one of our customers and load and view the newly added ArcGIS map for him, Could you guide me from where can I start in SDK? since you already implement it in Wialon.
I need to load this ArcGIS map using Wialon SDK or by remote API.

FYI:
ArcGis hosted on the following server: www.iraq-gis.com{
I can get an image for each request in the browser like this:  https://www.iraq-gis.com/mahala/{z}/{y}/{x}
How Wialon can render this ArcGis map on UI for the user as you have done?

Regards,
Thanks
