How to transpile (convert to older JS) array.at(-1) in CRA with react-script 4.0.3

Can I easily transpile array.at(-1) in project made with Create React App with react-script 4.0.3. I need this because it is not compatible with Safari. As far as I know CRA automatically transpile to older JS version with babel. Is the reason that it doesn't work with array.at() because react-script 4.0.3. has old babel that doesn't know how to transpile array.at()?

My setting in package.json are:

"browserslist": {
  "production": [
    ">0.2%",
    "not dead",
    "not op_mini all"
  ],
  "development": [
    "last 1 chrome version",
    "last 1 firefox version",
    "last 1 safari version"
  ]
},

in .gitlab-ci.yml I use following scripts

script:
  - npm install
  - npm run build --prod
