Include order details with flow generated email

[Uni-Trend]

Hi,

I created a workflow to alert me when specific items get ordered. 

I am able to get the flow to work, based on the conditions, as shown here:

What I am not able to figure out is how to include the order number that triggered the flow in the email, so I know which order to check. 

Any suggestions on how to include this would be fantastic. 

Thanks in advance,

Pete

To update, I found the Add Variables to message option.

I can get {{order.customer.displayName}} to work, but I cannot figure out how to call {{ order_number }}. I tried both just the order number and {{ order.order_number }} but that's not valid. 

Showing the customer name is good, but the order number (or even better a link to the order) would be even better.
