Module parse Error Typescript - Appropriate loader

[lsprung-tgm]

Hi, in my angular project I am unable to load 4 instances. I believe thats because of operations like ?? or ||.

This is one of the Errors:

ERROR in ./node_modules/@material/material-color-utilities/utils/theme_utils.js 101:27
Module parse failed: Unexpected token (101:27)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders_

| export function applyTheme(theme, options) {
> const target = options?.target || document.body;
| const isDark = options?.dark ?? false;
| const scheme = isDark ? theme.schemes.dark : theme.schemes.light;

Does anybody know how to configure a loader for a specific file?
