How can I fix a missing H1 tag in the Debut theme?

[oziomazart]

My SEO audit reveals an absence of H1 tag on my home page. I believe it’s referencing the logo. 
Please how can I modify this code in the header.liquid ?

<div class="grid__item {{ logo_classes }}">
{% comment %}
Use the uploaded logo from theme settings if enabled.
Site name gets precedence with H1 tag on homepage, div on other pages.
{% endcomment %}
{% if request.page_type == 'index' %}
<h1 class="h2 site-header__logo">
{% else %}
<div class="h2 site-header__logo">
{% endif %}
{% if section.settings.logo %}
{%- assign img_url = section.settings.logo | img_url: '1x1' | replace: '_1x1.', '_{width}x.' -%}
<a href="{{ routes.root_url }}" class="site-header__logo-image{% if section.settings.align_logo == 'center' %} site-header__logo-image--centered{% endif %}" data-image-loading-animation>
{% capture logo_alt %}{{ section.settings.logo.alt | default: shop.name }}{% endcapture %}
<img class="lazyload js"
src="{{ section.settings.logo | img_url: '300x300' }}"
data-src="{{ img_url }}"
data-widths="[180, 360, 540, 720, 900, 1080, 1296, 1512, 1728, 2048]"
data-aspectratio="{{ section.settings.logo.aspect_ratio }}"
data-sizes="auto"
alt="{{ logo_alt | escape }}"
style="max-width: {{ section.settings.logo_max_width }}px">
<noscript>
{% capture image_size %}{{ section.settings.logo_max_width | escape }}x{% endcapture %}
<img src="{{ section.settings.logo | img_url: image_size }}"
srcset="{{ section.settings.logo | img_url: image_size }} 1x, {{ section.settings.logo | img_url: image_size, scale: 2 }} 2x"
alt="{{ section.settings.logo.alt | default: shop.name }}"
style="max-width: {{ section.settings.logo_max_width }}px;">
</noscript>
</a>
{% else %}
<a class="site-header__logo-link" href="{{ routes.root_url }}">{{ shop.name }}</a>
{% endif %}
{% if request.page_type == 'index' %}
</h1>
{% else %}
</div>
{% endif %}
</div>
