Cannot use external content for rendering

[itpropro]

Environment

I try to create a simple plugin to display GitHub gists in a code block based on a gist URL. Due to multiple issues with the MDC component inside of a Markdown component and as I need it to already be embedded in the static content, I decided to create a plugin for that.
Unfortunately, as soon as there is a async ofetch request in the plugin, the file body is no longer updated. It is probably because of Nitro not supporting async plugins (@pi0 ?).

What is the current recommended way to add external content to your content files. There a many scenarios besides embedding GitHub gist code, where this would be helpful/necessary.

Reproduction

https://stackblitz.com/edit/nuxt-content-repro?file=server%2Fplugins%2Fcontent.ts

Commenting the async call out (line 18-21) makes it work. Also delete the content-cache and cache folder under .nuxt.

Describe the bug

Cannot request external content in content hook.
