1. Apply this diff (in order to actually initialize olm with WASM file since eventually it will be initialised when receiving notification in next diff): https://gist.github.com/marcinwasowicz/20ee184547487d05aa5421af8c77b107
2. Open web app.
3. In new tab open chrome://inspect/#workers
4. Go to `Service Workers` then `worker/notif` and finally click inspect. This should open a console.
5. Finally reload web app and ensure that no error is logged.
Repeat for prod and dev
