How to use the @ngrx/effects/schematics-core.addImportToModule function in @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];

    if (!options.minimal) {
      changes = changes.concat([effectsImport]);
    }

    const recorder = host.beginUpdate(modulePath);
    for (const change of changes) {
      if (change instanceof InsertChange) {
        recorder.insertLeft(change.pos, change.toAdd);
