Just to be clear, I need to have chosen "evade" as my action in order to use juke but I do not need to spend my evade token when I use juke, correct?

technically you don't have to evade as you action all juke cares about is that you have an evade token. and correct juke does not spend the evade

Precisely. In Second edition, the term "evading" simply means "have an evade token..." it doesn't matter where you got it from. For example, Juke works brilliantly on TIE Defenders and TIE Phantoms, thanks to their ship abilities to perform evade actions outside of the normal activation phase.

You could TECHNICALLY also put it on a small-base rebel ship with Lando, and hope your roll gives you an evade... but that's rather risky, IMHO.

or a ship with PerCo and Jyn

Rules Reference page 10:

"EVADE

"Pilots can evade to fly defensively. When a ship performs an [Evade] action, it gains one evade token.

"A ship is evading while it has at least one evade token."
