How to show Form response in modal box in Shopware 6?

I’ve created a form which is opened in a modal box thanks to this link:

Form

Is it possible to show the response of the form (the response of the controller of the form’s action) in the same modal box?

Is it possible without using js?

Did you find a solution?

Hello, can anyone tip on implementation of the same modal as standard Kontakt modal formular, but with another address using templates?
