@stale-optician-85950 Hello friend, I have been carrying out many tests and tried all the arguments that I had sent you to check the behavior of the chrome browser when executing the test by cypress and I find that it does not make any changes with respect to what I require, the browser launched by cypress does not change the behavior with all the arguments you send to it. I'll send you a detailed description of what's going on. First of all I share with you an image of what should happen when the test is executed, I did this test manually in the normal browser and as it is visualized in the image it is observed that when clicking the add button some fields are displayed. And the second thing is what happens when that same process is executed but from the test in cypress that, as we can see, does not allow the form to be displayed, it is as if it had a blockage. Then I was checking in code development mode and I see that it is generated as an error that I share here. that popup is shown but it does not disappear and it does not display the form, the strange thing is that if I do it in the normal chrome browser if it executes it well
