Note: browsers block some cross-origin requests because of CORS. For localhost and private-network APIs from a hosted page, the browser may also block or prompt for access, and your local server may need CORS enabled. The HTML Preview button can render returned HTML, while Open Preview can directly open the current URL, including localhost pages.
