While in a battle, select the "Menu" button in the top right corner, then select "Settings" at the top. Scroll down and you will find a section called "Auto Battle Settings." There is an option called "Enable Auto Brave Burst" which controls what you are asking about. When it is enabled, you have further options to customize auto battle: "Super Brave Burst Priority" and "Healing Brave Burst Priority."
