// Inspired from https://gist.github.com/petersvp/270f7d5d7d548448f4897586a0d389c0 and https://gist.github.com/Jimbly/9f6c6a0d9414310347f2803902ac7bb7

// 1. GO TO Steamworks, into the Query CD Key page, here: https://partner.steamgames.com/querycdkey/
// *Make sure your language is "English".
//
// 2. Having a Google Spreadsheet with the following format in a row:
// | KEY | Sent (checkbox) | Note | Activated |
// (You can modify the format by changing the Column constants.)
//
// 3. Call validateKeyActivated_All or validateSheetKeyActivated_ActiveSheet.
//
// 4. Fill the Cookie from broswer.
// To find the Cookie, you can see this comment:
