Hello there,

Just wanted to make it easier for other natives to interact with your amazing interface.

All the best.

Thanks for submitting this translation.
There are a few changes we need to make before rolling this out.

You are also missing a test, use this example from a recent French translation we added as a reference.

Also, make sure to run npm run format and then npm run lint to make sure the linter requirements are satisfied.
