Scheduled meeting opens in New Outlook instead of old outlook

[Zoom_GC]

Whenever I schedule a Zoom meeting on my desktop, the email invite opens in the old version of Outlook instead of the New Outlook, which I prefer to use. I've already set the New Outlook as my default email app in my system settings, but Zoom still defaults to the old version. ICS files are set to open in New Outlook btw. Does anyone know how I can fix this so that Zoom opens email invites in the New Outlook? Any help would be appreciated!
