How to set condition to true in Dialogflow CX

Question

I'm going through the Dialogflow CX tutorial and can't seem to understand how to set a condition to true.

From the tutorial:

tut p.1

From the reference:

tut p.2

I simply don't get the how and where I'm supposed to set this condition to true?

I have the following flow working as intended, except for the "true condition above".

To set a condition to true, please utilize the “Customize expression” condition rule. As seen below, this will automatically trigger the conditional route every time the page is active.
