How do you install the Managed File Transfer into the workbench?

I installed the package `DRAFP.9.0.21.300_Linux-x86_64.z` but continue to receive the error message for a File Transfer job.

_Control-M Managed File Transfer Deployment Package version 9.0.21.300 is installed_

`{
  "errors": [
    {
      "message": "Control-M module of type FILE_TRANS was not found"
    }
  ]
}`
