title: Accessing a Value in ENUM in a mongoose Schema
body: <p>I'd like to access a specific value from an array enum in mongoose. I am fully aware that  i can get the whole enum by <code>DocumentModel.schema.path('user_role').enumValues</code> but in the context below, i'd like to access the value <code>Buyer</code> under <code>user_role</code>.</p>
  <p>The Schema looks like :</p>
  <pre><code>const userSchema = new mongoose.Schema({
   user_role: {
          type: String,
          default: &quot;Supplier&quot;,
          enum: [&quot;Buyer&quot;, &quot;Supplier&quot;],
      },
      user_fullName: {
          type: String,
          required: true
      },
  )}
  </code></pre>
