 An _Azure Logic app_ is used to solve the problem of syncing files from SharePoint to blobs in the StorageAccount. This is not done directly by the API as there was some lacking permission features in the MS Graph API at the time.
 It also translates a SharePoint List (Product) into a .csv file ("metadata.csv") that is loaded to blob storage.
