Need some one to figure out how to get Tradingview indicator's protected source code (Pinescript) then teach me how to do it.

If you are familiar with Tradingview then you will know that we can apply indicators to our chart. Problem is sometimes these indicators are private, meaning you can still add them to your chart but cannot see the source code of that indicator (Pinescript) written by the author. I managed to use Chrome Debugger tool to debug the Javascript and get the Pinescript of public indicators (See screenshot attached). However, with my limited skill in Javascript I could not do the same for the private ones but I'm pretty sure it is still possible using the same method, we just need to work-around all the authentication mode and stuff for private ones. If you are experienced in Javascript this should not be too hard for you. After you figure out how to get Pinescript of a private indicator, then I would like you to show me how to do it myself. Since I have a little bit of background in programming I would be able to learn quickly.
