Share button for copying current URL

I use datasette in an iframe inside another HTML file that contains other ways to represent my data (mostly leaflets maps built with R on summarized data), and the datasette iframe is a tab in that page.

This particular use prevents users to access the full URLs of their datasette views and queries, which is a shame because the way datasette handles URLs to make every view or query easy to share is awesome. I know how to get the URL from the context menu of my browser, but I don’t think many visitors would do it or even notice that datasette uses permalinks for pretty much every action they do. Would it be possible to add a “Share link” button to the interface, either in datasette itself or in a plugin?

I really like the way the Share feature on Stack Overflow works: https://stackoverflow.com/questions/18934149/how-can-i-use-postgresqls-text-column-type-in-django

One possible treatment:

<style>
a.action-button {
    display: inline-block;
    border: 1.5px solid #666;
    border-radius: 0.5em;
    background-color: #ffffff;
    color: #666;
    padding: 0.1em 0.8em;
    text-decoration: none;
    margin-right: 0.3em;
    font-size: 0.85em;
}
</style>
<p>
    {% if query.sql and allow_execute_sql %}
        <a class="action-button"
            title="{{ query.sql }}"
            href="{{ urls.database(database) }}?{{ {'sql': query.sql}|urlencode|safe }}{% if query.params %}&amp;{{ query.params|urlencode|safe }}{% endif %}">
            View and edit SQL
        </a>
    {% endif %}
    <a href="#" class="action-button">Copy and share link</a>
</p>
