While you’re developing the app, it will be marked “private” and visible only to you. You can test it in Easel, and when it’s working the way you expect, you can notify us (on the forum) that it’s ready for review. We’ll be building out a more automated way to submit it for review in the future, as well as potentially more testing tools. We’d like feedback about how we can make all of this better for developers.
The documentation on the existing code should be updated to note that when developing the app the “Requires selected shape?” checkbox next to the editing window needs to be checked.
