How to use ToC with ContentRendererMarkdown?

[gitFoxCode]

Hi, I'm using nuxt-content to generate articles, but in some articles, I wanted to fetch a value from another article. Everything works correctly except for generating the ToC – useContent() ignores everything that is fetched from useAsyncData. How can I change this/delay the ToC generation until useAsyncData has completed (because I think that's where the problem lies)?

Example:

GetCustom.vue:

<template>
    <div class="w-full">
        <ContentRendererMarkdown :value="data">
            <template #empty>
                <p>No content found.</p>
            </template>
        </ContentRendererMarkdown>
        <ContentSlot unwrap="p" />
    </div>
</template>
<script setup>
const props = defineProps({
    url: String
})
const { data } = await useAsyncData('article', () => queryContent('/external-markdown-files/' + props.url).findOne())
</script>

MainArticle.md:

:GetCustom{url="article1"}

## Some heading

/external-markdown-files/article1.md:

## Heading 1
test
## Heading 2

ToC from const { toc } = useContent() only includes headings from MainArticle.md (## Some heading)
