package.json exports and multiple type declaration file

I am trying build a TypeScript library and want to export using exports field in package.json.

From nodejs and webpack’s documentation, I saw that exports is the recommended way to export modules.

https://nodejs.org/api/packages.html#package-entry-points

https://webpack.js.org/guides/package-exports/

The old way is to use “main”, “types” and “module”.

How can I export type declaration using this method?
Should I keep using the “types” field? But what if I have multiple exports?

Here is a sample of exports I have

"exports": {
    ".": {
      "import": "./dist/A.mjs",
      "require": "./dist/A.js"
    },
    "./A": {
      "import": "./dist/A.mjs",
      "require": "./dist/A.js"
    },
    "./B": {
      "import": "./dist/B.mjs",
      "require": "./dist/B.js"
    }
  }
