I don’t know, if that was not the idea to click everywere and find this link, the steps would have been explicited in the notification for the todo … Afterall, it’s explained in the section where you would expect it to be explained.. Now the direct link sounds like a huge spoiler though :p
I’d say anything that gives points is a challenge, reading and looking things by yourself is an important skill to have if you want to solve other challenges
People can make a challenge out of the simplest things. ;)
That said, there could be a more obvious way to the list. Like a link in the medals page or something or even just when you click on the To-do counter.
