Kohjah Breese's solution isn't working to detect Brave on Android (e.g. Chrome is detected as Brave). But as he said "If you search DuckDuckGo for [what's my user agent] they will return Brave." Then you can use the API of Duckduckgo to know if they browser is Brave :

request.open('GET', 'https://api.duckduckgo.com/?q=useragent&format=json', true)

  var isBrave = data['Answer'].includes('Brave');
  if(isBrave){
    console.log( isBrave );
  }
}

request.send()
