Embed attachment on pdf conversion

I am trying to save attachments from a word document while converting to PDF. I have a 16.2.0 jdk license. I do not see the setEmbedAttachments() option. Is there any other alternative?
If not, then which version would support this?

@aartiP I am afraid, there is no way to export embedded OLE object to PDF using old version of Aspose.Words. The PdfSaveOptions.EmbedAttachments property has been introduced in 22.11 version of Aspose.Words:
