Change terminal in visual studio code by iTerm2 with Powerlevel10k

I'm trying to change my VScode terminal. I have followed this tutorial.

My iTerm terminal has been changed perfectly :

I tried to edit my settings.json files in VScode like this :

{
    "terminal.external.osxExec": "iTerm.app",
    "terminal.integrated.shell.osx": "/bin/zsh",
    "terminal.integrated.fontFamily": "'SourceCodePro+Powerline+Awesome Regular'"
}

But i got this different result :

I can't understand why the parameters are not the same and some images do not pass in VScode.
