So I ended up doing the code below with some online help - putting this in the </> Customisal HTML of the forms Settings. This uses the plugin Popup Maker- you will need to replace "#popmake-5034" with your own popup form and re-direct img src = to your own information image  stored in your website media.   <div id="frm_field_[id]_container" class="frm_form_field form-field [required_class][error_class]">
    <div id="field_[key]_label" class="frm_primary_label">[field_name]
        <span class="frm_required" aria-hidden="true">[required_label]</span>
    </div>
    <div class="frm_opt_container" aria-labelledby="field_[key]_label" role="group">
        [input]
        <a href="#popmake-5034" class="popup-button">
            <img src="https:www.xyz.com/wp-content/uploads/2023/09/information-picture.svg" alt="Information" width="16" height="16">
        </a>
    </div>
    [if description]<div class="frm_description" id="frm_desc_field_[key]">[description]</div>[/if description]
    [if error]<div class="frm_error" role="alert" id="frm_error_field_[key]">[error]</div>[/if error]
</div>   So the form is as below and "Cyber Tip" is what pops up from Popup Maker one the information i is clicked
