Resolved, was using the old version of AppLayout 1.0.1 that comes by defualt with Vaadin Flow 13. I added a separate dependency in my pom for newer version 2.0.1 as follows:

<dependency>
            <groupId>com.vaadin</groupId>
            <artifactId>vaadin-app-layout-flow</artifactId>
            <version>2.0.1</version>
</dependency>

Thanks

Another problem. I have the following declaration for my appLayout:

<link rel="import" href="../bower_components/polymer/polymer.html">
<link rel="import" href="../bower_components/vaadin-app-layout/src/vaadin-app-layout.html">
<link rel="import" href="../bower_components/vaadin-tabs/src/vaadin-tabs.html">
<link rel="import" href="../bower_components/vaadin-tabs/src/vaadin-tab.html">
<link rel="import" href="../bower_components/vaadin-app-layout/src/vaadin-drawer-toggle.html">

<dom-module id="main-layout">
    <template>
        <style include="lumo-typography lumo-color">
            :host {
                display: block;
            }
        </style>
        <vaadin-app-layout>
            <vaadin-drawer-toggle slot="navbar"></vaadin-drawer-toggle>
            <img src="../img/GPpnszs.png" alt="Vaadin Logo" width="100" height="31" slot="navbar" referrerpolicy="no-referrer">
            <vaadin-tabs orientation="vertical" style="margin: 0 auto; flex:1;" theme="minimal" slot="drawer">
                <vaadin-tab>
                    Home
                </vaadin-tab>
                <vaadin-tab>
                    Cargo
                </vaadin-tab>
                <vaadin-tab>
                    Process
                </vaadin-tab>
            </vaadin-tabs>
        </vaadin-app-layout>
        <div class="content" style="width: 100%; height: 100%;">
            <h3>Page Title</h3>
            <p>Page Content</p>
        </div>
    </template>

    <script>
        class MainLayout extends Polymer.Element {
            static get is() {
                return 'main-layout';
            }

            static get properties() {
                return {
                    // Declare your properties here.
                };
            }
        }

        customElements.define(MainLayout.is, MainLayout);
    </script>
</dom-module>

My drawer comes by default hidden, how do I make it open when page loads and be side by side with my content DIV? Do i need to stype it or what?
