Cannot pass metabase.SESSION cookie between domains

Get Help
1

I'm trying to integrate an application on "domain-a.com" with the metabase on "domain-b.com" and for that I'm using the "POST /api/session" API that allows me to pass a username and password to receive the session ID. In order for the metabase to identify the user's session I need to have a "metabase.SESSION" cookie with the ID but when I try to assign this cookie between different domains the metabase doesn't identify the cookie.

I've tried switching between cookie sending settings (httpOnly=true, sameSite=Lax, domain=domain-b.com) but without success.

I've tried changing the "MB_SESSION_COOKIE_SAMESITE=none" parameter but the metabase stops working as it should.

Could someone please help me?

Today I have backend service to bypass CORS like this:

const express = require('express');
const axios = require('axios')

const app = express();

app.use((_req, res, next) => {
  res.setHeader('access-control-allow-headers', '*');
  res.setHeader('access-control-allow-methods', '*');
  res.setHeader('access-control-allow-origin', '*');
  res.setHeader('access-control-allow-credentials', 'true');
  next();
});

app.get('/api/session', ({query: {metabase_url, ...query}}, res) => {
  const url = new URL(metabase_url)
  url.pathname = '/api/session';
  axios
    .post(`${url}`, query)
    .then(response => {
      res.cookie('metabase.SESSION', response.data.id);
      res.redirect(`${url.protocol}//${url.host}`);
    })
    .catch(error => res.status(error.status).json(error.response.data));
});

module.exports = app;

Note: when metabase is located in localhost and my API running in localhost, it works but when domains are different isn't.
