I’m trying to customize the Optimize SEO page, specifically the website.TitleDescription section.

I found the original template as follows:

<t t-name="website.TitleDescription">
    <section>
        <div class="row">
            <div class="col-lg-6">
                <div class="mb-3">
                    <label for="website_meta_title">
                        Title <i class="fa fa-question-circle-o" title="The title will take a default value unless you specify one."/>
                    </label>
                    <input type="text" t-model="seoContext.title" t-att-disabled="!props.canEditTitle" class="form-control" placeholder="Keep empty to use default value" maxlength="70" size="70" t-ref="autofocus"/>
                </div>
                <div class="mb-3">
                    <label for="website_meta_description">
                        Description <i class="fa fa-question-circle-o" t-att-title="props.previewDescription"/>
                    </label>
                    <textarea t-model="seoContext.description" t-att-disabled="!props.canEditDescription" name="website_meta_description" placeholder="Keep empty to use default value" class="form-control"/>
                    <div t-if="descriptionWarning.length" class="alert alert-warning mt16 mb0 small">
                        <span t-esc="descriptionWarning"/>
                    </div>
                </div>
                <div class="mb-3" t-if='props.canEditUrl'>
                    <label for="website_seo_name">
                        Custom Url <i class="fa fa-question-circle-o" t-att-title="props.seoNameHelp" />
                    </label>
                    <div class="input-group">
                        <div class="input-group-prepend">
                            <span class="input-group-text seo_name_pre" t-esc="seoNamePre"/>
                        </div>
                        <input type="text" class="form-control" t-att-placeholder="props.seoNameDefault"
                               t-on-input="_updateInputValue" t-att-value="seoContext.seoName"/>
                        <div class="input-group-append" title="Unalterable unique identifier">
                            <span class="input-group-text seo_name_post" t-esc="seoNamePost"/>
                        </div>
                    </div>
                </div>
            </div>
            <div class="col-lg-6">
                <div class="card-header">Preview</div>
                <div class="card mb0 p-0">
                    <div class="card-body">
                        <SEOPreview isIndexed="props.isIndexed" title="title" description="description" url="url"/>
                    </div>
                </div>
            </div>
        </div>
    </section>
</t>

I created an inherited template as follows:

<?xml version="1.0" encoding="UTF-8" ?>
<templates xml:space="preserve">
  <t t-name="custom_Optimize_seo.TitleDescriptionInherit" t-inherit="website.TitleDescription">
    <xpath expr="//input[@t-model='seoContext.title']" position="after">
        <div class="est_ccs">
            <h1>Test</h1>
        </div>
    </xpath>
  </t>
</templates>

And my manifest file looks like this:

'assets': {
    'web.assets_frontend': [
        # 'theme_vcs/static/src/scss/style.scss',
    ],
    'web.assets_backend': [
        # 'website/static/src/components/dialog/seo.xml',
        'custom_Optimize_seo/static/src/xml/seo_template.xml',
    ],
},

However, it’s not working as expected.

Could you please help me check the code?
Thank you very much!
