Thank you for headsup, checked ntfy, nice project. It would be unfortunately unusable for NWC use case, as the wallet do not have access to the received notifications.

In case of NWC my server subscribes to encrypted NWC commands published to minibits relay, reencrypts them with own keys and routes them to the right device based on event recepient tag. They are not shown to the user, just used as data carrier passing the commands from relays to the device.
