Hello,

I’m trying to create a custom preview for a custom block. This is just a try. I’m totally new to plugins. I followed [the custom preview guide](https://getkirby.com/docs/reference/plugins/extensions/blocks) but nothing happened in the panel.

**/site/blueprints/blocks/element.yml :**

```auto
name: Élément
icon: circle
tabs:
  contenuTab:
    fields:
      contenu:
        type: textarea

```

**/site/plugins/element/index.php :**

```auto
<?php

Kirby::plugin('lineaire/element-block', []);

```

**/site/plugins/element/index.js :**

```auto
panel.plugin("lineaire/element-block", {
    blocks: {
      button: `
        <div class="element__content" @click='open'>
          {{ content.contenu }}
        </div>
      `
    }
  });

```

**/site/plugins/element/index.css :**

```auto
.element__content {
    border: 2px solid #000;
    display: inline-flex;
    border-radius: 3rem;
    padding: .25rem 1.5rem;
    cursor: pointer;
}

```

No result :

The block is called element, not button?
