How can I change permanently env variable in cypress.json?

I have sundry spec.js files to run. To increase tests performance and speed, I' ve created a first test file that login into my web service and store the token into an env variable called TOKEN that I' ve declared in cypress.json

{
  "env": {
      "TOKEN": ""
 },
  "viewportWidth": 1920,
  "viewportHeight": 1080,
  "responseTimeout": 90000,
  "defaultCommandTimeout": 60000,
  "requestTimeout": 60000
}

To do this I write the following code into the first test file:

describe('Setup', () => {

    it('Should setup token', () => {
        cy.request({
            method: 'POST',
            url: 'path/to/endpoint', 
            headers: {
                'api_version': Cypress.env('API_VERSION')
            },
            body: { 
                userName: Cypress.env('USERNAME'), 
                password: Cypress.env('PASSWORD')
            }
        }).then((response) => {
            Cypress.config('TOKEN', response.body.token)
        });
    });
});

The POST call works and it return and save the TOKEN in the cypress.json but It is available only for the first test file, when I go ahead with other test files (according to the documentation) the stored token value is deleted, because the Cypress.config('VAR_NAME', var_value) works only on the test file that has used the statement.

I' ve tried to store the token value into a cookie and save permanently the cookie but the token is too long and cannot be stored into the cookie.

Is there a way to save the token into the cypress.json env PERMANENTLY?

I think the simplest way to overcome the "only current spec" problem is to run your request in a before() in /cypress/support/index.js

// support/index.js

before(() => {
  cy.request({
    method: 'POST',
    url: 'path/to/endpoint', 
    ...
  }).then((response) => {
    Cypress.config('TOKEN', response.body.token) 
  });
})

When I run a couple of simple validation tests

// support/index.js
Cypress.config('test', 'test1')

// tests 1 & 2
it('sees globally set config', () => {
  expect(Cypress.config('test')).to.eq('test1')
})

it passes
