I looked at this link, which talks about changing the default shell in the integrated Visual Studio Code Terminal. I managed to change it to Git Bash using the setting in the file below settings.json. You can open the file settings.jsonby pressing the key combination Ctrl+ ,or the menu File → Settings → Settings menu:
{
"terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe"
}
There is a sign in the integrated terminal +with which you can have several terminals working in parallel, as shown in the screenshot below:

I want to load the Git Bash shell into terminal No. 1, Windows PowerShell into terminal No. 2, etc. Which appropriate configuration does the same?
