如何告诉ckeditor5在默认情况下使用我的自定义标题类型

我正在使用

@ckeditor/ckeditor5编辑器的自定义构建-classic@18.0.0

    heading : {
        options: [
            {
                model            : 'inlineParagraph',
                view             : 'span',
                title            : 'Inline Paragraph',
                class            : 'ck-heading_paragraph_inline',
                converterPriority: 'highest'
            },
            { model: 'paragraph',  title: 'Paragraph', class: 'ck-heading_paragraph' },
            { model: 'heading1', view: 'h1', title: 'Heading 1', class: 'ck-heading_heading1' },
            { model: 'heading2', view: 'h2', title: 'Heading 2', class: 'ck-heading_heading2' },
            { model: 'heading3', view: 'h3', title: 'Heading 3', class: 'ck-heading_heading3' },
            { model: 'heading4', view: 'h4', title: 'Heading 4', class: 'ck-heading_heading4' },
        ]
    }

当编辑器中没有文本时，我希望

inlineparagration

成为默认类型，默认情况下，编辑器选择

段落

我也试过：

    heading : {
        options: [
            {
                model            : 'inlineParagraph',
                view             : 'span',
                title            : 'Inline Paragraph',
                class            : 'ck-heading_paragraph_inline',
                converterPriority: 'highest'
            },
            { model: 'paragraph', view: 'span', title: 'Paragraph', class: 'ck-heading_paragraph' },
            { model: 'div', title: 'Div', class: 'ck-heading_div' },
            { model: 'heading1', view: 'h1', title: 'Heading 1', class: 'ck-heading_heading1' },
            { model: 'heading2', view: 'h2', title: 'Heading 2', class: 'ck-heading_heading2' },
            { model: 'heading3', view: 'h3', title: 'Heading 3', class: 'ck-heading_heading3' },
            { model: 'heading4', view: 'h4', title: 'Heading 4', class: 'ck-heading_heading4' },
        ]
    }

但是它选择了

div

作为默认值。。。我认为它默认为块级元素。。。但是我想把它改成一个内联元素，比如

span
