To get an element inside an iframe using Cypress, you can use the cy.iframe() command to select the iframe element and then use normal Cypress commands to interact with elements inside the iframe. For example, you can use cy.iframe().find() to locate an element inside the iframe and then perform actions like clicking, typing, or asserting on that element. Make sure to use the cy.iframe() command before performing any actions on elements inside the iframe to properly scope the commands.
