ReCaptcha v3 always has a score of 0.1 points. In chrome secret mode

I recently added reCaptcha v3 to my site. with this package It is React/Next.js/JavaScript project.

It works. When I tested it, it was 0.9 points. My colleague's script is 0.7 points.

It looks like pretty Good.

But, When I use Chrome Secret mode, I always get 0.1 point.

It is bug? or function ??
