How to use the @microsoft/rush-lib.Utilities.parseScopedPackageName function in @microsoft/rush-lib

public getTempProjectNames(): ReadonlyArray {
    const result: string[] = [];
    for (const key of Object.keys(this._shrinkwrapJson.dependencies)) {
      // If it starts with @rush-temp, then include it:
      if (Utilities.parseScopedPackageName(key).scope === RushConstants.rushTempNpmScope) {
        result.push(key);
      }
    }
    result.sort();  // make the result deterministic
    return result;
  }
