Where is the @$$#&%= back button lg stylo 4?

Like the Browser a lot but there is no back button so its terrible to try&surf on my phone. If anyone knows how to go back i would really appreciate it. The phones back button disappears when you launch brave. On my old phone i used the phones back button. On the lg stylo 4 its not an option.
