How to modify data in Edge Config using SvelteKit

[AakashGoplani-Nagarro]

Query 1:

I am following this example to update edge config using Vercel API. However since this is not a recommended approach, I tried invoking it via Edge Config API but I get 404 Error. Can you please let me know how to updated edge config?

<PUT> => https://edge-config.vercel.com/<id>/items?token=<token> => 404 NOT FOUND

Query 2:

I tried to implement above scenario using SDK as well but I was not able to find relevant example for Update operation. All examples were related to Reading the values from Edge Config. Other hurdle is - I am using SvelteKit, so while working with SDK, what is equivalent of NextRequest and NextResponse?
