How to send request with binary body (fime) using Cypress

I'm studying Cypress and now I'm writing test cases for API. I want to send a request with image src. My code (default request with json body):

 it('default request with json', () => {
  cy.request({
    method: 'POST',
    url: `${Cypress.env('api')}/request`,
    headers: {
      Authorization: access_token
    },
    body: {
      username: "Andy"
    }
  }).then((response) => {
    expect(response.status).to.eq(200)
  })
})

Can you help me to create similar request, but with binary body, to send image src?
