Any examples of using the library to connect to an on-premise Qlik Sense Enterprise cluster? here is an example of my config object:

const config = {
host: "xxxx.xxxx.com",
port: "4747",
isSecure: true,
appname : "xxxxxxxxxx",
rejectUnauthorized : false,
ca: ['-----BEGIN CERTIFICATE-----\nxxxx\n-----END CERTIFICATE-----'],
key: '-----BEGIN RSA PRIVATE KEY-----\nxxxxx\n-----END RSA PRIVATE KEY-----',
cert: '-----BEGIN CERTIFICATE-----\nxxxxxxx\n-----END CERTIFICATE-----',
headers: {
'X-Qlik-User': UserDirectory='INTERNAL'; UserId='sa_api',
}
}

export default function Browser() {

const engine = useConnectEngine( config );

return (

);

};
