Are there any cases and tutorials about using Hono/vercel with Websockets?

[Dilettante258]

I'm trying to replace my next.js backend with hono.js, and I also want to integrate websockets. But I don't know how to configure api/[[...route]]/route.ts properly.

import api from '@/server/api'
import { handle } from 'hono/vercel'


const handler = handle(api)

export {
    handler as GET,
    handler as POST,
    handler as PUT,
    handler as DELETE,
    handler as PATCH,
    handler as OPTIONS,
    handler as HEAD,
}

How should ws be introduced?
