ng-packagr extend rollup config

Question

I have a Custom Angular Library and I would like to customize the build of that Library using postcss.

Like the Angular Libraries are built using ng-packagr, I need to extend the rollup.config.js of ng-packagr to customize the build of my Library.

In fact, I would like to use postcss through rollup like is used here: https://www.learnwithjason.dev/blog/learn-rollup-css/

I saw in the documentation of ng-packagr that is possible to extend the rollup config: https://github.com/ng-packagr/ng-packagr/blob/master/docs/DESIGN.md#rollup-config

However, I didn't find any documentation or example on how to do that.

Does anybody know how to do that?

Can anybody provide me an example?

Thanks in advance.
