Redirecting to other page from popup contact form DAWN

Hi, I´ve duplicated the contact form and added this to a popup that opens up when customers click on a contact icon on my site. Everything is working as wanted except from when my customers are supposed to enter their details and send the form. When clicking send I´m being redirected to another page. How can I implement both recaptcha, error messages and success messages inside the popup without being redirected to another page?

Here is the code:

{{ "section-contact-form.css" | asset_url | stylesheet_tag }}

{%- style -%} .section-{{ section.id }}-padding { padding-top:
{{ section.settings.padding_top | times: 0.75 | round: 0 }}px; padding-bottom:
{{ section.settings.padding_bottom | times: 0.75 | round: 0 }}px; } @media
screen and (min-width: 750px) { .section-{{ section.id }}-padding { padding-top:
{{ section.settings.padding_top }}px; padding-bottom:
{{ section.settings.padding_bottom }}px; } } {%- endstyle -%}

  

  

    

      ## 
        {{ section.settings.heading | escape }}
      
      {{section.settings.contact_paragraph}}

      
      

{{section.settings.contact_email}}

      

{{section.settings.contact_address}}

    

    

    
      {%- form 'contact', id: 'ContactForm', class: 'isolate' -%} {%- if
      form.posted_successfully? -%}
      

        {% render 'icon-success' %}
        {{ "templates.contact.form.post_success" | t }}
      

      {%- elsif form.errors -%}
      
        ## 
          {% render 'icon-error' %}
          {{ "templates.contact.form.error_heading" | t }}
        
      

      
        - {{ form.errors.translated_fields["email"] | capitalize }}
              {{ form.errors.messages["email"] }}
          
        
      

      {%- endif -%}
      
        

          
          
        

        
          
          
        

      

      
        
        
        {%- if form.errors contains 'email' -%}
        <small>
          {{ "accessibility.error" | t }}
          {% render 'icon-error' %}{{
              form.errors.translated_fields["email"] | capitalize
            }}
            {{ form.errors.messages["email"] }}
        </small>
        {%- endif -%}
      

      
        
        
      

      
        
      

      {%- endform -%}
