Can the host (Go via wasmtime) call a named function inside a Javy-compiled WASM module?

[Calrain]

Hi team,

We’re embedding a Javy-compiled WASM module in Go using wasmtime-go.
We already have a Javy plugin that exposes host functions back to JavaScript and that works well.

What we’d like to do next is have the Go host call a specific JavaScript function (exported from the Javy module) directly — essentially instance.GetFunc("my_js_func").Call(...).

Is this supported with Javy’s runtime model, or does Javy wrap QuickJS in a way that prevents direct host-to-guest function calls?
If it’s possible, could you point to an example or best practice for doing this safely?

Thanks!
