How is this supposed to be configured by the user? Does it not support distinct connections mode?

I'm having issues getting the client to send POST requests (distinct connections mode) instead of PUT requests (single connection mode).

Nice catch, we need to pass options in

graphiql/packages/graphiql-toolkit/src/create-fetcher/createFetcher.ts

Lines 50 to 52 in 2936a79

	const sseFetcher = await createSseFetcher({
	url: options.subscriptionUrl,
	});
