Mimekit / mailkit download message body?

Question

I recently made my own email client and added the receive option, I used mimekit and mailkit as plugins and could download most of my emails to the reader, who should show the content (right now it shows the subject, until, from, date)

How I downloaded the theme to ..., msg.envelope.subject, msg.envelope.to But I can not load the body as follows :( when executing msg.body, msg.textbody, msg.bodyparts, ... they are all lead to NOTHING, the place where it should be is just empty, I can’t get it downloaded :(

Can anybody help me?
