Themes Magento 2.4-生成通过composer安装的主题的子主题父主题

我需要小费。 我已经通过composer安装了一个主题，我需要创建一个子主题，并将一个通过composer安装的主题作为父主题

通过编写器安装的主题路径：vendor/{vendor}/{theme}/ 子主题路径：app/design/frontend/{vendor}/{theme}/

在我创建的子主题文件夹中： theme.xml

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
    <title>TitleTheme</title>
    <parent>{folder-name-vendor}/{folder-name-theme}</parent>
    <media>
        <preview_image>media/preview.jpg</preview_image>
    </media>
</theme>

    'frontend/{my-vendor-folder}/{my-child-theme}',
    __DIR__
);
