Google lens search history

So apparently Google finally provides this functionality as an opt in privacy option in your Google account. The thing is though.. the check box and line "Include visual search history" isn't there in my account settings. It's supposed to be under Data & Privacy => Web & App Activity. Is this still in AB testing or being rolled out per region or...??

Thanks for anyone who can help me find an answer. I've been wanting this feature for a long time and google can't provide me with an answer to this question.
