Google Assistant doesn't work with Custom Intents

Question

Google assistant doesn't catch the custom intent. I've implemented custom intent and it triggers fine from Test Tool. It works from Test Tool just fine.

But I can't figure out how to register this capability or shortcut in google assistant so it starts resolving the requests.

It works perfectly with BII.

Custom intent(shortcuts.xml):

<shortcuts xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

    <shortcut
        android:shortcutId="GET_STATUS"
        android:shortcutShortLabel="@string/assist_get_status"
        android:enabled="true">
        <capability-binding android:key="custom.actions.intent.GET_STATUS"/>
    </shortcut>

    <capability
        android:name="custom.actions.intent.GET_STATUS"
        app:queryPatterns="@array/assistant_queries_get_status">

        <app-widget
            android:identifier="GET_STATUS_WIDGET"
            android:targetClass="<MY APP ID>.ui.assistant.GetStatusWidgetProvider"
            android:targetPackage=<MY APP ID>
            <extra android:name="hasTts" android:value="true"/>
        </app-widget>

        <intent
            android:identifier="GET_STATUS_FALLBACK"
            android:action="android.intent.action.VIEW"
            android:targetClass="<MY APP ID>.ui.assistant.GetStatusWidgetProvider">
        </intent>
    </capability>
</shortcuts>

Query patterns:

<string-array name="assistant_queries_get_status">
    <item>(to)? get (my)? status</item>
    <item>(to)? check status</item>
    <item>how is home</item>
    <item>get (my)? sensors statuses</item>
    <item>what is the status (at home)?</item>
    <item>how is the house</item>
    <item>provide (a)? status report</item>
</string-array>

In manifest I have:

    <receiver
        android:name=".ui.assistant.GetStatusWidgetProvider"
        android:exported="false">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/button_widget" />
    </receiver>

    <service
        android:name=".ui.assistant.GetStatusWidgetProvider"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="com.google.assistant.appactions.widgets.PIN_APP_WIDGET" />
        </intent-filter>
    </service>

And I added shortcuts meta-data to launch activity as well.

The query I tried: "Hey Google, ask TEST APP how is home?" and it doesn't work.

If I change the capability and shortcut to actions.intent.GET_EXERCISE_OBSERVATION (and remove queryPatterns of course) and try something like: "Ask TEST APP, "How many miles have I run today?"." - it works!

I also ran an internal test in GP, logged in the same account in Android Studio as on my test device, the same that I use in GP to publish and internal testing - all the same. From Test Tool - works, from Assistant - nope.

I can't understand if I missed something or it's a bug.

Any help is highly appreciated, thank you!
