[QC2168]

If there are multiple contentScript scripts, how should the package file be set up

[QC2168]

// vite.config.content.ts
  build: {
    watch: isDev
      ? {}
      : undefined,
    outDir: r('extension/dist/contentScripts'),
    cssCodeSplit: false,
    emptyOutDir: false,
    sourcemap: isDev ? 'inline' : false,
    lib: {
      entry: [r('src/contentScripts/index.ts'), r('src/contentScripts/scan/index.ts')],
      name: packageJson.name,
      formats: ['iife'],
    },
    rollupOptions: {
      output: {
        entryFileNames: 'index.global.js',
        extend: true,
      },
    },
  },

Multiple entry points are not supported when output formats include "umd" or "iife".
error during build:
