Tests

3. Confirm the design matches the updated layout in https://github.com/Expensify/Expensify/issues/167278#issuecomment-982972716

Looks good.
Not affected by this PR, but I think we should update the error message

Looking pretty good! I forget where we landed with this general UX discussion, but should we actually move the green button to be at the very bottom of the disclosure text instead of being fixed to the bottom of the viewport? I think that makes sense given that you basically need to scroll all the way to the bottom and tap on the checkboxes before moving forward. Thoughts on that?
