There is no such option. But you can use any of subscription plugins of Wordpress https://www.formget.com/email-subscription-wordpress-plugins/

Hi 

I follow your article for making subscribe form for mailchimp, but when i want to subscribe is open new tab and there again you need to enter the infos.

When i use elementor pro and subscribe form, when i ones the email is entered in the list, when you try to enter again the same email, it has message that is successfully entered.

Can you give me any advice to make when email is entered to have message confirmation is needed, and mail for confirmation to be send. When person confirms the email in that point email address to be added to the list.

Thanks
