How to remove this windows: brave set as default

Hello,
Since today, I have this window which appears almost every time brave is launched, how do I remove it? I click on not now but it has no effect, it reappears at the next launch Brave!!!
Thank you
Greetings

Sorry, I’m using a French / English online translator
