What does BringOwnFeatureNotEnabled error code means in Azure

Question

I am trying to Create Form Recognizer through ARM. I am getting this error while passing the Key Vault details for encryption with customer managed key. I am getting this error only when attaching key vault details. Even Azure portal is also showing this error. can anyone please explain what does it means.

"error": {
    "code": "InvalidTemplateDeployment",
    "message": "The template deployment 'TestFormRecognizerdeployment' is not valid
 according to the validation procedure. The tracking id is '367569de-8774-4ef9-a158
-a82132f19e0d'. See inner errors for details.",
    "details": [
      {
        "code": "BringOwnFeatureNotEnabled",
        "message": "Bring your own feature is not enabled for Subscription/SKU/Kind
."
      }
    ]
  }

My understanding you are trying to make use of customer managed key. Before making use of it you will have to fill out the request form here :

Cognitive Services Customer Managed Keys and Bring Your Own Storage access request

Once this has been approved (usually takes around 5 business days).Upon the Approval, the feature responsible for the customer managed key will be activated/enabled on the subscription. You should be able to get passed the mentioned error.
