Uncaught Error: Class “SimpleHistory” | WordPress.org

I am querying the Simple History API using the example Query API – Simple History (simple-history.com) here. However, I am getting a fatal error for the class ‘SimpleHistory’. Is there a workaround to this?

For reference here is my code

function register_simple_history_api_endpoint() {
    register_rest_route('simple-history/v1', '/history', array(
        'methods'  => 'GET',
        'callback' => 'get_simple_history_entries',
    ));
}
add_action('rest_api_init', 'register_simple_history_api_endpoint');

function get_simple_history_entries() {
    $log_query = new SimpleHistoryLogQuery();
	$simple_history = SimpleHistory::get_instance();
    $query_results = $log_query->query([
        'posts_per_page' => 99,
    ]);

    if (is_wp_error($query_results)) {
        return $query_results; // Return any error that occurred while fetching the entries.
    }

    $output="";

    printf(
        '
        <p>Found %1$d rows.</p>
        <p>Viewing page %2$d of %3$d.</p>
        ',
        esc_html($query_results['total_row_count']),
        esc_html($query_results['page_current']),
        esc_html($query_results['pages_count'])
    );

    $log_rows = $query_results['log_rows'];

    if (!empty($log_rows)) {
        $output .= '<ul>';

        foreach ($log_rows as $row) {
            $header_output = $simple_history->getLogRowHeaderOutput($row);
            $text_output = $simple_history->getLogRowPlainTextOutput($row);
            $details_output = $simple_history->getLogRowDetailsOutput($row);

            $output .= '<li>';
            $output .= '<hr />';
            $output .= '<p>' . $header_output . '</p>';
            $output .= '<p>' . $text_output . '</p>';
            $output .= '<p>' . $details_output . '</p>';
            $output .= '</li>';
        }

        $output .= '</ul>';
    }

    return $output;
}
