Metfields - Shopify - Code Snippet (trying to add product color swatch via metafield and Code Snippet) - shopify

Question

I'm trying to display a color-swatch on the product page in which clicking on a product's color redirects to another product url. The way I've done this is set-up the metafields in Shopify Settings (picture displayed below)
[1]: https://i.stack.imgur.com/RsSCa.png
And then created a Code Snippet in the theme's code called " linkedProducts.liquid", code displayed below:
{% assign linked = product.metafields.my_fields.linked_products | split: ',' %}
{% assign linkedcolors = product.metafields.my_fields.linked_products_colors | split: ',' %}
{% assign linkednames = product.metafields.my_fields.linked_products_names | split: ',' %}
{% assign size = linked | size %}
{% assign currentHandle = product.handle %}
{% if size > 0 %}
<div class="linkedColors custom_swatch_elements">
<label class="single-option-radio__label label-color_swatches" data-label="Color">
Color
</label>
<div class="swatch clearfix" data-option-index="1">
{% for i in (1..size) %}
{% assign index = i | minus:1 %}
{% assign color = linkedcolors[index] | strip %}
{% assign name = linkednames[index] | strip %}
{% assign url = linked[index] | strip %}
<a data-value="{{ color }}" class="swatch-element {% if currentHandle == url %}active{%endif%}" href="{{shop.url}}/products/{{url}}">
<label class=" linkedLabel text-center text-ellipsis" style="background:{{color}};"></label>
<div class="tooltip spacer-bottom text-center">{{ name }}</div>
</a>
{% endfor %}
</div>
</div>
{% endif %}
<style>
.linkedColors{
}
.linkedLabel{
cursor:pointer
}
.swatch-element.active{
border:1px solid #292929 !important;
}
</style>
The store theme used is debutify (v 4.9.0), store url https://miesha.com.au/collections/bottoms/products/aura-scrunch-black
As you can see, the product color swatch does not show (if you see color swatches there it is the native debutify color swatch addon (as shown when inspected).
Please do let me know if there is a solution to this as it is giving me a headache.
