basemap-gallery and arcgis-map components and USA style

Question

My organization’s AGOL is configured to use the U.S. style (e.g. Gulf of America), but I see Gulf of Mexico on my initial map.  When I change my basemap (via the basemap gallery) it shows Gulf of America from then on.  How does one configure the arcgis-map component so the initial basemap also honors the required style?

Unrelated to the above, the basemap-gallery component has about 35 maps by default.  I struggled a bit trying to specify a subset of basemaps to present the user with but I was not successful and would appreciate any code snippets (I think it’s in the view model but I couldn’t get it working).

Our organization is set up for the United States and all of our basemaps in AGOL show up the way I need them to, it just doesn't work in my custom application.  In my sample code (see GitHub link in my previous post) I iterated through the basemaps and tried loadedBasemap.style.worldview = 'unitedStatesOfAmerica' but that didn't work either.  I'm at a bit of a loss as to what else to try.

Looking at this blog post, it looks like you would need to set it up in your organization.

I haven't done this, but you might be able to go through each one and assign the region in Map Viewer.

Thanks for the input @ReneRubalcava, with your suggestion I was able to figure out how to subset the basemaps in the gallery, however, with regards to the US worldmap style, now I am having the opposite problem where I can get the first map to show the US perspective, but the gallery basemaps revert to the non-US perspective.  I've posted my test application at https://github.com/VolpeUSDOT/basemap-sytle.  Thanks!
