Add SponsorBlock and DeArrow into Brave iOS

Hello, I think that you should try to add SponsorBlock and DeArrow to Brave iOS into the (optional) features that are disabled by default, because nowadays in addition to YouTube’s ads (which are blocked by default), the creators have started to put sponsors into their videos and also use clickbait titles. Using and integrating these two can effectively skip the sponsors/interactions remainders and more, and also remove the clickbait titles to make the videos experience on YT more concise and spot-on than that of without the 2 extensions. You can get help from Ajay for these 2 functionalities to be implemented.
