Cookie not set

Hi, When calling in BROWSER http://localhost:3000/membre/identification/setcookie, cookie is set correctly. But when this api url is called by http request from my angular application (http://localhost:4200/home), cookie is not set. I don’t undersand why.

IdentificationController.ts:

...
@Get("/setcookie")
    setcookie(@Session() session, @Req() request: Request, @Res() response: Response)
    {
        session.membre = {}
        session.membre.id = 'OK';		
        session['membre'] = 'AZERTY';
        return session;
    }
// return  {"cookie":{"path":"/","_expires":null,"originalMaxAge":null,"httpOnly":true,"domain":"localhost","sameSite"
:false,"secure":false},"membre":"AZERTY"}

    
    @Get("/getcookie")
    getcookie(@Session() session, @Req() request: Request, @Res() response: Response)
    {		
        return {'session': session};
    }
// return {"session":{"cookie":{"path":"/","_expires":null,"originalMaxAge":null,"httpOnly":true,"domain":"localhost"
,"sameSite":false,"secure":false}}}
...

app.

expressApp.use(session({
        secret: 'cookie_secret',        
        resave: true,
        saveUninitialized: true,
        cookie: {
            //domain: 'localhost',
            sameSite: false,
            path: '/', 
            httpOnly: true, 
            secure: false, 
            maxAge: null
        }
    })); // use session middleware

Web browsers do not allow that to happen for security reasons. For example, if you try to set a cookie on google.com from your site, when you then go to google.com that cookie is not set, because the web browser just ignored it for security reasons. We can only work within the limitations web browsers impose on cookies.

I suppose i should use proxy servers.
