    path: "m/44'/1237'/0'/0/0",
    showOnOneKey: true,
});

Return a bundle of public keys for multiple ethereum accounts:

HardwareSDK.nostrGetPublicKey(connectId, deviceId, {
    bundle: [
        { path: "m/44'/1237'/0'/0/0" }, // account 1
        { path: "m/44'/1237'/0'" }, // account 2

        npub: string,        // npub
    }
}

Result with bundle of public keys

{
    success: true,
    payload: [
        { path, publickey, npub }, // account 1
        { path, publickey, npub }, // account 2
        { path, publickey, npub }, // account 3
    ]
}
