Let's say you need to install cors on the server and do the configuration, but here's the problem. I use Svelte for my application, but I use as the main api not my own, but the api that is located on this link. But I can't configure the cors there, what should I do? Moreover, all attempts on the frontend to somehow change the cors, setting access-control-allow-origin and other headers, making the proxy server did not work. How to get out of this situation, I have a deadline soon.
