Cypress - How to do polling in Cypress?

On web application, particular element is visible only after page reload and that is also available after some time, so currently I have implemented it as below:

it('element-check', () => {
    cy.visit('url')
// performing certain actions 
    cy.wait(150000)
    cy.reload()
    cy.contains('text').click()
})

instead of fixed wait cy.wait(150000), I need to use the polling mechanism in such a way that after every 30 seconds the page is getting reloaded and check for the required element until the element is visible.

You can use a recursive function to achieve this.

it('element-check', () => {
  cy.visit('url')

  let retry = 0
  function isElementVisible() {
    
    if (retry < 5 && Cypress.$('selector').length == 0) {

      //Increment retry
      retry++

      //wait 30 seconds
      cy.wait(30000)

      //Reload Page
      cy.reload()

      //Element is not yet visible, Call the recursive function again
      cy.then(isElementVisible)

    } else if (retry < 5 && Cypress.$('selector').length == 1) {
      cy.get('selector').click()
      return

    } else {
      //It excedded required no. of execution
      return
    }
  }
  //Trigger the recursive function
  cy.then(isElementVisible)
})
