I am new to VSCode and and trying to switch from Eclipse and this is becoming already painful.My end goal is to reconnect an existing project I already created with an existing Sandbox. I already created the project and did some work. Then I had to witch to another org and I created a new project, but now I need to switch back to my original Project and Org. So What I did is in VSCode I selected File - Open Folder, and selected my project. But now I need to authorize. When I hit Ctrl+Shift+P and type sfdx, I do not see the sfdx Authorize Org. What am I missing?
