Associate Discord Server Invite Links With Discord Through xdg commands

Whenever I click a server invite link in my browser for example, I get the xdg-open popup window which in turn opens my browser with a link in the following format:

discord:///invite-proxy/some numbers

I'm relatively familiar with xdg-mime commands, but I'm not sure what the "filetype" I should be associating with my discord.desktop file should be. Anyone that can help?

Thanks
