我是新手，我想在 Google Apps 脚本中创建一个代码，该代码将执行以下操作
1. Create some test labels in my Mail box
2. Then accordingly fetch these mails in User's drive using Google cloud SQL (i have used script db)
3. Once a folder for a label is created change the owner of that folder to admin of domain
4. Now i have to import all these email from drive to Admin's mailbox using Email migration Api
我已经做到了step 3。我不知道如何4th part通过编码进行。任何人都可以建议
