maybe refer to the gallery in the task tab after completing the tasks? Took me some time to find it on accident. Was about to close the game with content still left uncovered.
Might wanna add something to show, that there are more scenes to be unlocked and not just "this is the end of content". Because I found more content, but only through the "Find list" you posted.
Also, when I hack the ventalation system and go down the elevator I just landed inside of the droid and got caught instantly. I had 0 chance, because I couldn't see where he is when going down.
So I just started playing and am on the 4th task, I am stuck here and can't go in both directions, because the ledge is too high and the platform went back upstairs.
