Injection is using the build-scripts command. It is using the inject script inside of scripts/inject. Currently testing with map.html. The purpose of this is to be injectable into any vanilla html project via script tag and data set html tag. Test the map.html inside the dist folder once it's done building.
You will need to add your domain to sanity's CORS Origins list otherwise you will recieve a cors error and the dealers will not return.
Go to The Outdoor Group Dealer Locator sanity project located here: https://manage.sanity.io/projects/kzfz2ho3. You will then navigate to settings > api > CORS Origins and add your domain there. That should prevent a CORS error from popping up.
