How to set Access-Headers to public assets directory access

[takutope]

Nuxt3 SSR production build creates some mjs and css files in .output/public/_nuxt/ directory.
I would like to set access header "Cache-Control": "max-age=31536000" for static assets access via nitro.

I tried config like below, but it does not work.

 {
    publicAssets: [
      {
        maxAge: 31536000,
      }
    ]
}

Is there any solution?

I've been trying this config on nitropack api and it is not working for me too

for me it works with this:

export default defineNuxtConfig({
  routeRules: {
    '/_nuxt/**': { headers: { 'cache-control': 'max-age=31536000,immutable' } }
  }
})

Actually I think this should be the default for the _nuxt directory.
