Expose external_id in embed.js

I am needing to load posts on an external site where I don’t know the post_id but I DO know the external_id that I configured when I created the topic. Can someone please expose the external_id variable in the embed.js logic or teach me what I’m missing? Example support needed: window.DiscourseEmbed = { discourseUrl: ‘https://forums.blah.org/’, external_id: ‘2023-4’ };
