I'm working with app proxies to request Shopify admin API but there is an issue. I can connect to the custom API and receive the response successfully. But when I'm trying to connect Shopify API using custom API, it is not working.
I see that the issue is `session` which is undefined when I'm trying to call a request from the Theme extension. So my question is how can I get the session and send it to Shopify API when I'm calling the request from the Theme extension?
