Filters the string in the ‘more’ link displayed after a trimmed excerpt.

Replaces ‘[…]’ (appended to automatically generated excerpts) with an
ellipsis and a “Continue reading” link in the embed template.

function wp_embed_excerpt_more( $more_string ) {
	if ( ! is_embed() ) {
		return $more_string;
	}

	$link = sprintf(
		'%2$s',
		esc_url( get_permalink() ),
		/* translators: %s: Post title. */
		sprintf( __( 'Continue reading %s' ), '' . get_the_title() . '' )
	);
	return ' … ' . $link;
}
