I have an app where I a progress bar for chapters, when a chapter is pressed associated lessons appear, thereafter a lesson can be chosen and the lesson content is shown. What I want to implement is that when lessons is completed and the green check is clicked the progress bar for the chapter should reflect that and increase.

Here is the project: https://codesandbox.io/s/runtime-wave-1tbk0?file=/src/Landing.js:1145-1159
