How to download OneDrive/SharePoint attachments off messages (email) using Graph API?

Question

I have a requirement where I have to download the content that is attached to the emails in my organisation.

Scenarios include

• when a user is on OneDrive/Sharepoint and they go to share a file via email. A 'sent' email gets generated in said users emails.
• when a user is on Outlook -> New message -> Attach file -> OneDrive -> Send. A 'sent' email gets generated in said users emails.

I can access these emails, but the problem is I am unable to download the actual content. For instance the attachments endpoint (when I share via OneDrive):

https://graph.microsoft.com/v1.0/users/{user-id}/messages/{msg-id}/attachments

Returns the actual attachments on the email (i.e. images). I am able to extract a href off the body content but I do not know how to download the content that is linked? i.e.

https://sharepoint-my.sharepoint.com/:x:/g/personal/administrator/<id?>>?e=4%3a0uILKI&amp;at=9\

When I attach when a new email is created:

https://sharepoint.sharepoint.com/:w:/t/TestTree/<id?>

Again I don't know how to download the content that is being linked in the href.

Any idea how I can do this guys? Thanks
