The email sent to a customer who was refunded via PayPal needs updating.

How can I update the template so that it says PayPal instead of an unknown credit card?
HI Firstly i would like to as a few questions
- Where is your email template stored?
- How is the payment method currently referenced in the template?
- Do you want PayPal to always show, or only when PayPal was used?
- in Shopify
- you didn’t see the image I posted?
- only when used
I believe this is the part of the code that isn’t working:
{% if transaction.kind == ‘refund’ and transaction.gateway != “shop_offer” %}
{% if transaction.payment_details.credit_card_company %}
{% assign refund_method_title = transaction.payment_details.credit_card_company %}
{% else %}
{% assign refund_method_title = transaction.gateway_display_name %}
{% endif %}
i’ve solved this by adding the following code:
{% if transaction.gateway == "paypal" or transaction.gateway_display_name contains "PayPal" %}
<p class="customer-info__item-content">
<img src="{{ 'paypal' | payment_type_img_url }}" class="customer-info__item-credit" height="24">
<span>PayPal</span>
</p>
