I try add style support for file block in gutenberg.

my code work for UL/li list:

wp.blocks.registerBlockStyle('core/list', {
    name: 'blue-circle',
    label: 'Blue Circle',
});

I try add:

wp.blocks.registerBlockStyle('core/file', {
    name: 'test-inline',
    label: 'test-inline',
});

no work for file block.
Anyone know how I can add support for file block? on the core HTML block?

Thanks!
