const gateway = new Gateway();
        await gateway.connect(ccpPath, { wallet, identity: 'admin', discovery: { enabled: true, asLocalhost: true } });

        // Get the CA client object from the gateway for interacting with the CA.
        const client = gateway.getClient();
        const ca = client.getCertificateAuthority();
        const adminUser = await client.getUserContext('admin', false);

 

 

I get this for Gateway for a console.log -
