I highly recommend reading this: So, what's next?

core-js-compat package contains data about the necessity of core-js modules and API for getting a list of required core-js modules by browserslist query.

1import compat from 'core-js-compat';
2
3const {
4  list,                       // array of required modules
5  targets,                    // object with targets for each module
6} = compat({
7  targets: '> 1%',            // browserslist query or object of minimum environment versions to support, see below
8  modules: [                  // optional list / filter of modules - regex, string or an array of them:
9    'core-js/actual',         // - an entry point
10    'esnext.array.unique-by', // - a module name (or just a start of a module name)
11    /^web\./,                 // - regex that a module name must satisfy
12  ],
13  exclude: [                  // optional list / filter of modules to exclude, the signature is similar to `modules` option
14    'web.atob',
15  ],
16  version: '3.43',            // used `core-js` version, by default - the latest
17  inverse: false,             // inverse of the result - shows modules that are NOT required for the target environment
18});

`targets` option

targets could be a browserslist query or a targets object that specifies minimum environment versions to support:

1// browserslist query:
2'defaults, not IE 11, maintained node versions';
3// object (sure, all those fields optional):
