I have successfully connected VS Code and pushed to several different SF environments, including Trailhead, Developer, and Production. But I can't figure out how to push to a sandbox. It looks like you can't connect to a sandbox the same way you would with another org (using SFDX: Authorize an Org from the command palette), but when I do it directly from the command line
sfdx force:auth:web:login -r https://test.salesforce.com/
it seems to work (I get a message in terminal that I've
Successfully authorized <mySandboxUsernam> with org ID <myOrgId>)
But after authorizing, if I try to right-click on a folder to deploy, I don't get a contextual menu option of
SFDX: Deploy Source to Org as I would when authorized with other instances. Is there any way to push code to a sandbox? I don't mind doing it from the command line if that's the only way, but I can't find any documentation on how to do it.
