I guess that there’s a misunderstanding of the terms
‘warp’ is a terminal emulator application
but VSCode integrates command shells like bash, zsh, etc.
terminal apps in most cases it’s GUI apps that allow you to work with a command shell. In this case VSCode’s terminal window it’s a terminal app. that’s why you can’t just use ‘warp’ or any other GUI terminal emulator inside the VSCode environment.
