d2oracle: How to Set a Markdown label?

[NorbertHauriel]

I am trying to programmatically create D2 diagrams, using d2oracle package.
But when calling d2oracle.Set to add Markdown labels, it always inserts the Markdown as a regular, quoted string:

value := `|md
# MyTitle
testing this markdown syntax
`
graph, _ = d2oracle.Set(graph, nil, "mykey.label", nil, &value)

Can I work around this in an intuitive way, or did I miss something?

Thanks for creating D2!
