GetAttachments
The GetAttachments activity is used with the File Upload component in Forms Builder. The activity returns an array of files uploaded through the File Upload component as UploadStorageEntity[].
To access all the attached files, you can use a ForEach loop to iterate over the array; or, if a single file is attached, access the file contents as UploadStorageEntity(0).FileData.
