intercept / wait a specific request in a series of of requests to the same URL

[gkatsanos]

I'm trying to evaluate the payload of GA request , the url is always https://www.google-analytics.com/collect .
The problem is that there's 3 events triggered, of which I want to evaluate / wait only the last one.
The code looks a bit like:

Cypress.Commands.add("submitForm", (productScaling) => {
  if (productScaling) {
    cy.get("#delivery_location").type(faker.location.city())
    cy.get("#delivery_time").type(JSON.stringify(faker.date.future()))
    cy.get("#quantity").type(faker.number.int(1000))
    cy.get("#surface_treatment").type(faker.number.int(100))
  } else {
    cy.get("[data-test=reason-select]").click() // triggers a GA event
    cy.get("[role=menuitem]").eq(faker.number.int(3)).click() // triggers another GA event
    cy.get("[data-test=department-select]")
      .click()
      .within(() => {
        cy.get("[role=menuitem]").eq(faker.number.int(1)).click()
      })
  }

  cy.get("#full_name").type(
    faker.person.firstName() + " " + faker.person.lastName()
  )
  cy.get("#email").type(faker.internet.email())
  cy.get("#message").type(faker.lorem.sentence(30))
  cy.get("[data-test=submit-request]").click() // triggers another GA event , triggers an HTTP POST request
})

After this form is submitted and sent to an API with POST, there's a final GA event triggered which is the one I'm trying to wait/intercept.

How do I do that?
