 * You will most likely want to use {@link @backstage/app-defaults#createApp},
 * however, this low-level API allows you to provide a full set of options,
 * including your own `components`, `icons`, `defaultApis`, and `themes`. This
 * is particularly useful if you are not using `@backstage/core-components` or
 * Material UI, as it allows you to avoid those dependencies completely.
