Can not call embed files

Getting Help Code Review
1

I’m embedding my css and js files as below:

package resources

import (
	"embed"
)

// WebUI is our static web ui from onsen ui.
//go:embed public/onsen
var WebUI embed.FS

// Views is our static web server layouts, views with dynamic content and partials content that is a static view.
//go:embed templates/layouts templates/views templates/partials
var Views embed.FS

And trying to define this WebUI as static folder in my main function:

package main

import (
    "fmt"
    "log"
    "html/template"
	"net/http"
	"onsen/resources"
)

var view *template.Template
var err error

func init() {
	fmt.Println("Starting up.")
	view = template.Must(template.ParseFS(resources.Views, "templates/layouts/*.html", "templates/views/*.html", "templates/partials/*.html"))

	if err != nil {
		log.Fatal("Error loading templates:" + err.Error())
	}
}

func main() {
	http.Handle("/static/", http.StripPrefix("/static/", http.FileServer(http.FS(resources.WebUI))))
	//http.Handle("/static/", http.FileServer(http.FS(resources.WebUI)))

    http.HandleFunc("/index", index)
    server := http.Server{
		Addr: "127.0.0.1:8070",
	}
    server.ListenAndServe()
}

func index(w http.ResponseWriter, r *http.Request) {
	err = view.ExecuteTemplate(w, "index.html", nil)
	if err != nil {
		log.Fatalln(err)
	}
}

The folders structure is as shown:

But a running, I’ getting the below errors:

CSS files: Refused to apply style from 'http://127.0.0.1:8070/static/css/onsenui.css' because its MIME type ('text/plain') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

JS files: Failed to load resource: the server responded with a status of 404 (Not Found)
