duckdb-wasm with jest

[nite]

Does anyone know how to get duckdb-wasm working in jest? I'd like to write/test our browser duckdb code, and it has a more fully-featured api than node duckdb, and not need a façade wrapper to switch between them. The bare node example doesnt run, even updating the import to worker_threads, with an error:

TypeError: this._worker.addEventListener is not a function
    at f.attach (...@duckdb\duckdb-wasm\dist\duckdb-node.cjs:1:13364)
    at new f (...@duckdb\duckdb-wasm\dist\duckdb-node.cjs:1:13283)
    at ...node-duckdb.js:21:20

Had a look #1445 - not sure it helps. I may have asked this question yesterday, thought I posted it however don't see it anymore & may have been deleted - if it's a dupe, how could you please post me a link to the dupe before deleting?
