Video Block / CSS display: none

Hi David,

I'm using the WP standard video blocks to embed both youtube and self-hosted video. For YouTube Videos I need to remove the branding (see screenshot), but using the modestbranding-parameter is not working.

Alternatively, I have tried the display: none option in the Customizer using the following CSS:

/* WP video-block - w/o branding */

.ytp-chrome-top {
    display: none;
}

.ytp-impression-link {
    display: none;
	}

Any chance you can spare a minute and let me know what I'm missing in the CSS?

Thanks,
Jan
