Invalidate React Query on SSR Next JS (App Router)

I am using SSR React Query by following this guide - https://tanstack.com/query/latest/docs/framework/react/guides/advanced-ssr

I have a API that fetches me list of products.
I am using SSR react query to cache the response

my common queryClient file

import { isServer, QueryClient } from "@tanstack/react-query";

import { DEFAULT_QUERY_OPTIONS } from "@constants";

function makeQueryClient() {
  return new QueryClient({
    defaultOptions: {
      queries: {
        staleTime: 10 * 60 * 1000,
        refetchInterval: 10 * 60 * 1000,
      },
    },
  });
}

let browserQueryClient: QueryClient | undefined = undefined;

export function getQueryClient() {
  if (isServer) {
    return makeQueryClient();
  } else {
    if (!browserQueryClient) browserQueryClient = makeQueryClient();
    return browserQueryClient;
  }
}


and page where I am fetching the products

const qc = getQueryClient();

const Page = async () => {
  await qc.prefetchQuery({queryKey: ["products"], queryFn: getProducts});

  return (
    <HydrationBoundary state={dehydrate(qc)}>{children}</HydrationBoundary>
  );
} 


But my main issue is, when the Backend Data change, It takes upto 10 mins to update the data on frontend to validate it.
How can I clear the cache on server side from backend?

I tried create a api route in nextjs and create a POST API

const client = getQueryClient();

export async function POST() {
  client.invalidateQueries();

  return NextResponse.json({ success: true, message: "Cache cleared" });
}

But this doesn't work either.

The I replaced my getQueryClient Function with this as well

export const getQueryClient = cache(() => new QueryClient());


which didn't helped either.
Please suggest something that would help me, or would I need to remove the SSR from frontend?
