Questions about Webview/HTMLmenu Tutorial?

Curious why the example code for the web view / html menu has reference to adguard filter?

Is this portion necessary?

Nevermind, was able to remove those.. and its working just fine still

ah sorry, probably copy&paste from my side. I’ll remove it

While your poking around there, I don't know why, but none of the example photos were working for me. They all fail to load
