Warning Messages Babel/polyfill: Bump corejs to v3?

[tacman]

With Yarn 2, I"m getting a warning message about babel/polyfill. (It's in AdminkitPro, but I think it has the same issue for the free version).

In my webpack, I'm using

    // enables @babel/preset-env polyfills
    .configureBabelPresetEnv((config) => {
        config.useBuiltIns = 'usage';
        config.corejs = 3;
    })

Here's the error:
