Booster theme (third party developer)- hreflang tag code in shopify how to fix it

hai friends,

hreflang tag code in Shopify. my Shopify store had created with booster theme support. I want to place it in the theme. liquid-header, hreflang tag to place it but my store is a third-party tool which creates by booster theme. can you share the coding of hreflang tag based on en-US, en-CA, English-America, and Canada in the major target users for all product pages?

we have created sample codes is it correct, shall we place the code in theme. liquid

{%- comment -%} clickhere2shop {%- endcomment -%}

{%- assign original language = “en” -%}

{%- unless false -%}

{% for language in original_language %}

{% endfor %}

{%- endunless -%}

shall we use it for Booster theme (third party developer) above code
