Why doesn't autoprefixer work for scss modules in React?

Question

React

Good afternoon! I recently started learning react and I have a question. I use css modules to style the site, but I write them in scss, thanks to the scss => css compiler. But for some reason, the autoprefixer doesn't change the styles, and I see exactly the same thing in the browser as in the code editor. Help me to understand.

This is what browserslist looks like in the package.json file:

"browserslist": {
    "production": [
      "cover 99.5%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 2 chrome version",
      "last 2 firefox version",
      "last 2 safari version"
    ]
  },
  "devDependencies": {
    "css-loader": "^6.4.0",
    "sass-loader": "^12.2.0",
    "style-loader": "^3.3.0"
  }
