AndroidTV and OPEN_DOCUMENT_TREE Intent

Question

How do I find out if the ACTION_OPEN_DOCUMENT_TREE intent is supported on Android TV?

Targeting API 32 and using the StorageVolume createOpenDocumentTreeIntent call. I can create the intent, but when I attempt to launch it, I get:

"You don't have an app that can do this message".

My app can do that on Android Phones and Tablets, just not AndroidTV. My storage related permissions are:

  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
  <uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />

For Android TV support, I have added:

  <uses-feature android:name="android.software.leanback"
                android:required="false" />
  <uses-feature android:name="android.hardware.touchscreen"
        android:required="false" />

And my TV Activity is declared as:

    <activity
        android:exported="true"
        android:name="com.connectedway.connectedsmb.TvActivity"
        android:label="@string/app_name"
        android:theme="@style/Theme.Leanback">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LEANBACK_LAUNCHER" />
      </intent-filter>
    </activity>

The app comes up on Android TV fine, but when I try to bring up a picker, it fails with the "You don't have an app..." message. I'm thinking there isn't support for this on AndroidTV, but it could be something else.

It looks like Storage Access Framework is not included in Android TV:

I guess Android TV, is not quite Android.
