Auto-generate transforms for fields inside of Content Block fields

[alexroper]

Is it possible to auto-generate an image transform for a field inside of the new Content Block field type introduced in Craft 5.8?

https://craftcms.com/docs/5.x/reference/field-types/content-block.html

I've tried the following inside of the imager-x-generate.php config, but this doesn't seem to work.

return [
    'fields' => [
        'contentBlockField.image' => [
            'transformName',
        ],
    ],
    'elements' => [
        [
            'elementType' => \craft\elements\Entry::class,
            'criteria' => [
                'section' => ['blog'],
            ],
            'fields' => ['contentBlockField.image'],
            'transforms' => [
                'transformName',
            ]
        ]
    ]
];
