How to access $site from Vue panel component?

I need the contents from $site in my Vue panel component.

I tried to hand over with a computed value like this:

Kirby::plugin('my/plugin', [
    'blocks' => [
        'contact' => [
            'computed' => [
                'site' => "123yeah" // testing ...

But site in the Vue component is empty. What’s wrong, and isn’t there a documentation on that topic? I was looking around here Panel internals | Kirby CMS but did not find anything out there.

Thanks a lot

You can always get it via the api. In any case, you cannot pass data from php to the block component.

Wouldn’t it be possible to handover $site to the Component like content is available in the block, too?

What would the API-way to get $site look like?
