Typescript compiler does not convert String.prototype.replaceAll (ES2021) to target ES2020

I'm trying to compile my ts code with the target ES2020 as my node version is v14.17.3, according to the following tsconfig:

{
    "compilerOptions": {
      "target": "es2020",
      "lib": ["ESNext.String"],
      "module": "commonjs",
      "allowJs": true,
      "outDir": "./build",
      "esModuleInterop": true
    }
}

As String.prototype.replaceAll is not supported in node v14.17.3 I'm getting error when running the code below, probably because the compiler is not replacing replaceAll with a valid expression in the target ES2020:

const text = "my text"
const newText = text.replaceAll(' ', '-')
console.log(newText)

TypeError: text.replaceAll is not a function

Shouldn't Typescript compiler convert text.replaceAll(' ', '-') to a valid expression in the target ES2020?
