How to add a form to landing page (new builder)

How can I add a Form to a Landing Page using the new Builder?

The Shortcode {form=1} doesn’t work here. Can anybody help me? Thanks in advance!

Your software
My Mautic version is: 4.4.5
My PHP version is: 7.4.33
My Database type and version is: 10.6.11-MariaDB

Can you check the code and make sure there are no other characters between the letters in the code ?{form=1}
