Problem in Angular product build

[nowitz]

If I run project ng serve, everything is OK, plugin works.
If I create a production build and run it, I get this error:

I have imports:

and I tried imports:

import pluginNewsletter from 'grapesjs-preset-newsletter';
import {default as pluginNewsletter} from 'grapesjs-preset-newsletter';
import * as newsletterPlugin from 'grapesjs-preset-newsletter';

file tsconfig.lib.prod.json:

my code is:

or (I tried both plugin import examples)

dependencies:

"grapesjs": "0.21.3"
"grapesjs-preset-newsletter": "1.0.2"
"@angular/core": "16.1.3"
"@nx/angular": "16.4.3"

How should the import of the plugin look like or where am I making a mistake?
Thx
