First, create a Space where your forms will be developed. 

After creating a new space, click on "New Form".

It's important to select the target Space and the domain where the form will be hosted. Make sure the domain includes either "**http/https**" according to your website's configuration. Click on "Create".

You can define the fields of your form in the created field group. Each field can have its own CSS key, and you can also add reCaptcha and a color theme to the form. 

After saving the form settings, click on the three dots and select "Form HTML Code" to publish it.

You can find the form responses by going back one step, clicking on your Form Space, and then selecting "Open Submission Forms List" in the top right corner.

From the submissions, you can easily create a contact or a business case.
