Gnome Evolution Email - Saving my messages as a .PDF file issue

I wanted to save some Emails with all the formatting, images, and attachments, just as they appear in Evolution. I know I can 'File > Back up Evolution Data...' but I want it so I don't have to connect to the internet (IMAP server). I've tried following the advice here: https://help.gnome.org/users/evolution/stable/mail-save-as-pdf.html.en But when I click on the file name to select the destination, I can't go past the Username directory. What's even more absurd is that I can't find the **.PDF** anywhere in the Terminal! I also tried entering the code: gsettings set org.gnome.evolution.mail drag-and-drop-save-file-format 'pdf' I just get the message *No such schema “org.gnome.evolution.mail”* Evolution was installed as flatpak through the Fedora Software Center.
