 * `serverType` - either `SAS9` or `SASVIYA`.
 * `serverUrl` - the location (including http protocol and port) of the SAS Server. Can be omitted, eg if serving directly from the SAS Web Server, or in streaming mode.
 * `debug` - if `true` then SAS Logs and extra debug information is returned.
-* `LoginMechanism` - either `Default` or `Redirected`.  If `Redirected` then authentication occurs through the injection of an additional screen, which contains the SASLogon prompt.  This allows for more complex authentication flows (such as 2FA) and avoids the need to handle passwords in the application itself.  The styling of the redirect flow can also be modified.  If left at "Default" then the developer must capture the username and password and use these with the `.login()` method.
-* `useComputeApi` - Only relevant when the serverType is `SASVIYA`. If `true` the [Compute API](#using-the-compute-api) is used.  If `false` the [JES API](#using-the-jes-api) is used.  If `null` or `undefined` the [Web](#using-jes-web-app) approach is used.

 The adapter supports a number of approaches for interfacing with Viya (`serverType` is `SASVIYA`).  For maximum performance, be sure to [configure your compute context](https://sasjs.io/guide-viya/#shared-account-and-server-re-use) with `reuseServerProcesses` as `true` and a system account in `runServerAs`.  This functionality is available since Viya 3.5.  This configuration is supported when [creating contexts using the CLI](https://sasjs.io/sasjs-cli-context/#sasjs-context-create).
