UM Shortcodes

Can the UM shortcodes be used in emails that come from a different email platform?

I use FLuentForms for the registration page and have UM set to that page.
I have things set to require preapproval of the user
FLuentforms send an admin email to notify me when someone registers. I’d like to be able to add a link in that email to the pending user’s profile, but the shortcode doesn’t work, and the documentation doesn’t discuss this.

I’m using this [ultimatemember_account] is there something else that needs to go with it?

Can this be done or does it require coding?
