SharePoint left navigation bar in modern page

If you create a SharePoint site using the “communication site”, the left navigation is hidden and the top navigation menu appear. Which is different than the “Team Site” and there is no way to change it back unless you write code for custom branding. So need to beware of this when you create a SharePoint site. https://robertschouten.com/2017/11/10/modern-sharepoint-sites-navigation-options/
