How to process ItemAttachments attachments , I dont need to save it as in some folder as eml and all?

Question

Hi All,

My requirement is to get the attachment of an email and attach to my UI control, For attachments whose @odataType is ItemAttachments, they are not working as for those attachments we are not able to get details like content-type, contentBytes. For extensions falling under @odataType File Attachments, its working fine as we are able to get the content-type & ContentBytes.

I saw multiple places to use $value to get raw Mime Content Message, but curious once I get that MimeMessage what should be next steps such that I can get proper and correct content-type, ContentBytes.. Please see we should not get content-type as plain-text as we are getting while using $value in graph API End points
