-_Note on backwards-compatibility:_ If a **wallet service** supports both nip44 and nip04 for legacy client apps, it should publish both notification events for each notification - kind 23196 encrypted with NIP-04, and kind 23197 encrypted with NIP-44. It is up to the **client** to decide which event to listen to based on its supported encryption and declared supported encryption schemes of the **wallet service** in the `info` event.
