How to leverage Akonadi for emails in a Plasmoid

Hi! I didn't get any response in the channel, and the info said I could 
reach out here.

I'm learning how to make Plasmoids, and I'm. Wanting to make a widget for 
displaying emails.

How can I access a list of old emails, information about email, and capture 
new emails, in QML in a Plasmoid?

I've been examining the Akonadi dbus api with a dbus explorer, but I can't 
quite figure it out. I've searched online for documentation on the dbus 
api, and haven't really found anything.

Is there any documentation on how to directly use dbus for what I'm looking 
for? Or is there an alternative way to get emails via QML?

Thanks in advance!
