Create cache for webp files

[Messa]

Hi.

Do I need something to the config that generated webp also get cached?
In my config i have

return [
  'panel' =>[
    'install' => true
  ],
  'cache' => [
    'pages' => [
      'active' => true
    ]
  ]
]

I use that code to generate webp

->thumb(
                [
                    'width'     => 755,
                    'height'    => 550,
                    'crop'      => true,
                    'format'    => 'webp',
                    'quality'   => 80,
                ]
              );

But when I than check for example google page speed - I got the message “Statische Inhalte mit einer effizienten Cache-Richtlinie bereitstellen”
