How to use the @ngrx/effects/schematics-core.insertImport function in @ngrx/effects

const effectsModuleImport = insertImport(
      source,
      modulePath,
      'EffectsModule',
      '@ngrx/effects'
    );

    const effectsPath =
      `/${options.path}/` +
      (options.flat ? '' : stringUtils.dasherize(options.name) + '/') +
      (options.group ? 'effects/' : '') +
      stringUtils.dasherize(options.name) +
      '.effects';
    const relativePath = buildRelativePath(modulePath, effectsPath);
    const effectsImport = insertImport(
      source,
      modulePath,
      effectsName,
      relativePath
    );

    const effectsSetup = options.minimal ? `[]` : `[${effectsName}]`;
    const [effectsNgModuleImport] = addImportToModule(
      source,
      modulePath,
      `EffectsModule.forRoot(${effectsSetup})`,
      relativePath
    );

    let changes = [effectsModuleImport, effectsNgModuleImport];

const text = host.read(modulePath);
    if (text === null) {
      throw new SchematicsException(`File ${modulePath} does not exist.`);
    }
    const sourceText = text.toString('utf-8');

    const source = ts.createSourceFile(
      modulePath,
      sourceText,
      ts.ScriptTarget.Latest,
      true
    );

    const effectsName = `${stringUtils.classify(`${options.name}Effects`)}`;

    const effectsModuleImport = insertImport(
      source,
      modulePath,
      'EffectsModule',
      '@ngrx/effects'
    );

    const effectsPath =
      `/${options.path}/` +
      (options.flat ? '' : stringUtils.dasherize(options.name) + '/') +
      (options.group ? 'effects/' : '') +
      stringUtils.dasherize(options.name) +
      '.effects';
    const relativePath = buildRelativePath(modulePath, effectsPath);
    const effectsImport = insertImport(
