Solution

First, you need to open devtool and stop the anti-debugging debugger statement then disable that annoying animation. Some elements are hidden by ads-banner, so you need to disable adblockers to actually see them. The flag is also split into multiple span elements and ZWNJ, so you need to remove them to find the flag.
