To add a form almost anywhere in the teams area you need to first:
1). Create a form in the ‘gravity forms area’
2). Get the forms ID number.
3). Paste in the shortcode.
Shortcodes are bits of text in a pair of brackets like this:
[gravitform id="1" title="false" description="false" ajax="true"]
The id number is the number of the form you want to add to this page for example. You can read more HERE

HelpieWP also has some great documentation on its own shortcodes that you can use: https://helpiewp.com/docs/home/shortcodes/
