add tracking in email with order tracking plugin

I have your email template customizer plugin and I just bought the order tracking plugin in order to be able to add tracking info to the emails, but I’m not able to.

I want to add the tracking info, which is automatically added in the order notes by shipstation when I purchase a label through shipstation. I have the shipstation plugin set up and working fine.

I can’t figure out how to add the tracking info to the order completed emails. I just need to add it.

Can you please let me know how to do this?
