How can I add data from the USGS National Map server to ArcMap Desktop? I think I need to set up an API, but I am not sure how to do this and didn't have any success searching the internet. 

Specific goal is to load data and processed products like hillshades from the [TNM Download](https://apps.nationalmap.gov/downloader/#/) without having to download it locally, make a hillshade, etc.

I tried to add WMS Server  (as suggested at similar old question [here](https://gis.stackexchange.com/questions/222749/usgs-national-map-to-arcgis))but received an error: `Failed to connect to the server.`
