This attached image is my HTML code for href which will open a new tab
The DOM has iframe so I wrote below code accessed the href and it will open in new tab. I am unable to access the newly opened tab, though I know the method that would have target attribute so we remove that and open in same tab but here I don't have any target attributes.
Please check this and help to access my new tab.
cy.visit('https://yopmail.com/en/')
cy.get('.ycptinput').type('some_name {enter}')
cy.wait(2000)
cy.get('#ifmail').its('0.contentDocument.body').then(cy.wrap).find('a').click()
