Way to ‘remote clone’ my tablet
A possible solution is to backup the old phone with Helium - App Sync and Backup. Then upload, the data files created by it to Google Drive (or any other cloud storage). Download the data files from the cloud storage to your new phone. Finally restore them using the same app.

Obviously, your friend will do the backup and upload the files. While you will download and restore them.

Note: I don't own a Huawei phone, so I could not advise whether the app you mentioned will work or not.
