Can't figure out how to start designing site

So I’m new to using Local for WordPress. I just created a new site on Local. I can currently see all the stats, database, SSL, and utilities but I cannot figure out how to actually start designing my website. Nothing online tells me where in the application I can start doing this. I have several themes installed on my WordPress account online but I can’t even find a place to access them. I’ve heard people reference a gear button but I don’t have one anywhere on my application. Do I need to download another application to actually design the website? The only way I have been able to edit the visual part of the site is clicking the admin button for the site and going to WordPress on my browser which defeats the purpose of Local. I havce uploaded a screenshot of what I see on my application.Please help!
