SSO not work between Next.js applications

I have two applications on Auth0.

A: test1.com
B: test2.com

Both applications are Next.js(App Router) applications.

When I go to the login page of B after logging into A, it redirects me to the authentication page instead of redirecting to the successful login page of B.

Below is a code sample from my application. Could you please help me identify what is wrong?

  login: (req: NextRequest, ctx: AppRouteHandlerFnContext) => {
    return handleLogin(req, ctx, {
      authorizationParams: {
        connection: "email",
      },
    });
  },

Tenant settings are shown in the image below:
