Genesys JS SDK deleteUser 204 but interactions gone?

Using the usersApi.deleteUser method in the Genesys Cloud JS SDK. It returns a clean 204 No Content, but when I query the interactions API for that user ID later, the history is empty.

const response = await usersApi.deleteUser({ userId: '123' });
console.log(response.status); // 204

Does the SDK or API actually have a soft delete option that preserves interaction records? I just want to deactivate them, not nuke the history.
