Is it possible to attach a file from a shared folder instead of fixture folder ?

Hi,

I wonder if it is possible to attach a file from a shared folder instead of fixture folder, for example in code below, readFile and writeFile both work properly:

And(`Import file`, () => {
  const testName = 'cypress-test-' + moment(new Date()).format('YYYYMMDDTHHmmss');
  const importFile = '\\\\server\\path\\to\\UT\\Cypress\\MyTest\\' + testName + '.json';
  cy.readFile('\\\\server\\path\\to\\UT\\Cypress\\MyTest\\file.json').then(
    data => {
      data.name = testName;
      cy.writeFile(importFile, JSON.stringify(data));
    },
  );

  cy.get('#drop').attachFile(importFile);
});

But for attachFile I got following error (\server\path\to\UT\Cypress is actually repeated twice on each path):

A fixture file could not be found at any of the following paths:

> \server\path\to\UT\Cypress\server\path\to\UT\Cypress\cypress-test-20220119T144026.json
> \server\path\to\UT\Cypress\server\path\to\UT\Cypress\cypress-test-20220119T144026.json{{extension}}

Cypress looked for these file extensions at the provided path:

> .json, .js, .coffee, .html, .txt, .csv, .png, .jpg, .jpeg, .gif, .tif, .tiff, .zip

Provide a path to an existing fixture file.

Is it just this is mandatory to attach file from a fixture or it is possible to do it from a shared folder and I'm just doing it wrong ?
From error I guess this is only doable from fixture, but in the other hand there is a specific attachFixture function and I see in the readme that "attachFile on the other hand recognise cy.readFile, so a path within the project root folder needed" but as seen in my code readFile can actually also read a file from a shared folder, not only in "project root folder".

Thanks.
