Received this msg on my BRAVE Browser after 1-mth used: "Your +4.119 BAT July rewards will arrive in 7 days"

Received this msg on my BRAVE Browser after 1-mth used: “Your +4.119 BAT July rewards will arrive in 7 days”… what do I need to do:

  1. If I don’t do anything, will I lost my BAT rewards?
  2. How do I transfer my BAT rewards to my MetaMask wallet?

Thanks
