@Alexolini you’re going to the wrong place. Look at Save and Share just above. It got moved there a few updates ago. This was a chromium change and not specifically a Brave thing.
Also want to point out that once you do cast, you can right click on the cast button and pin it to the top (always show icon), which saves steps. What I mean is like you see below:
Omg, can’t belive i didn’t figure that out with all the trying and the googling i did 
You just made me happy and angry at the same time 
thank you so much, now i don’t have to switch browsers for casting anymore
