		 * Example:
		 *
		 *     add_filter( 'jetpack_connection_plugin_logos', function ( $logos ) {
		 *         $logos['my-plugin'] = plugins_url( 'assets/logo.svg', __FILE__ );
		 *         return $logos;
		 *     } );
		 *
		 * @since 8.3.2
		 *
		 * @param array<string,string> $logos Map of plugin slug to SVG URL.
