Tempex b36 movement click spring placement

[Primos843]

I was taking apart this movement and removed one of the bridges and accidentally dislodged the click and click spring. I have never worked on a movement like this and have zero clue how to reengage the click spring. Any ideas would be appreciated.

I can only find a couple of photos of watches with the back removed, no other details for that movement.

From the positions of the other wheels, I can only guess the spring must hook on the tall pin of the click and fit around the barrel? Either in that region, or literally on the outside of the barrel??
