Link to specific Office 365 Email

I would like to be able to create a Macro which creates a To Do item containing the URL link to a specific Office 365 email message (using the web, not using the Outlook desktop app).

I know this must be possible because the Zapier integration for Office 365 does make such a URL available. But i would prefer not to use Zapier if not necessary.

Does anyone know a way I could find the email message URL inside KM or inside a KM script so that I can then pass it on to my To Do program?
