Missing css while adding an extern angular project

[Franz-Ritter]

Thank you for sharing your approach to setup micro apps with angular/elements.
I tried to extend your example with a separate angular project which I than successful compile with ngx-build-plus. The application starts bus misses the css styles from the original project. The external project uses libraries like PrimeNg or bootstrap. It seems that the css information does not get passed. Is there a way to provide an angular custom element with all original css styles?
