Hi Michael,

I assume that your form extension produces the shortcode for the form. That shortcode can be inserted into the desired place using the Shortcode control.
As for the modules, please refer to this video and article:

create an RSform module give it a custom position e.g. my_contact_form
edit in Nicepage ~ add new block add(+) element Html
Click on the new HTML element so it highlighted
on the right side see code insert

            <style>

            <p>{loadposition my_contact_form}
            </p>
