I don't think I can activate brave rewards since I don't get any bar like everyone else.

Hello, sorry for the inconvenience, but I must know what happens here.
I have tried several things and none of them work apparently, it does not show me the option to activate or deactivate brave rewards, and that is disturbing me.
I would appreciate your help, thank you very much in advance.

Your Brave rewards are active. The switch you are referring to no longer exists.
