| <li><p>Using <cite>NO_AUTH</cite> mode, simply setup an insecure channel of connection.</p></li> |
| <li><p>Using <cite>SSL</cite> or <cite>TLS</cite> mode, supply a credential pem file for the connection id, |
| this will setup SSL or TLS secured connection with gRPC service.</p></li> |
| <li><p>Using <cite>JWT_GOOGLE</cite> mode. It is using google auth default credentials by default, |
| further use case of getting credentials from service account can be add later on.</p></li> |
| <li><p>Using <cite>OATH_GOOGLE</cite> mode. Scopes are required in the extra field, can be setup in the UI. |
| It is using google auth default credentials by default, |
| further use case of getting credentials from service account can be add later on.</p></li> |
| <li><p>Using <cite>CUSTOM</cite> mode. For this type of connection, you can pass in a connection |
| function takes in the connection object and return a gRPC channel and supply whatever |
| authentication type you want.</p></li> |
