Are US dollars accepted in Bora Bora?

Excuse me, could you please clarify for me whether or not US dollars are widely accepted as a form of payment in Bora Bora? I'm planning a trip there and want to make sure I have the right currency on hand. Is it necessary to exchange my dollars for the local currency, or are they readily accepted by businesses and establishments? Your input would be greatly appreciated as I try to prepare for my upcoming journey.
