Integrating Angular 9 app with Liferay 7.x portlet

Hello!

I have an Angular 9 app that I would like to make accessible via Liferay 7.x portlet.

When I follow these steps, deploy my portlet and try to render it, I run into issues (reported as JavaScript errors in the browser console):

1. "Can't bind to 'X' since it isn't a known property of 'Y'.
2. "'X' is not a known element:

A. If 'X' is an Angular component, then verify that it is part of this module.

B. If 'X' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message."
The problem is that as far as I can see the modules in question are properly annotated and listed as exports, declarations, etc.

I would appreciate help with resolving these issues. I am happy to jump on a Zoom to demonstrate the details of my config.

Thank you!
