I have an Android 10 tablet that offers Google Assist. I can use Duckduckgo and the Google Assitant app. There is no option to use Brave. Brave would be able to bypass Google features and become integrated with Android if allowed to be the Assist app of choice. Using new Android 10 gestures, swipe up from the lower right corner and use Brave. Easy way to gain some market share by power users.
