Thank you all for your ideas.
First, I was not able to find client_secret.json or token.json on my computer, maybe it is named differently, I'll try to look for something like that.
Second idea, to sign out... Well, I did log out from that computer and also unauthorised CodelabPreview chrome extension (just to be sure). However, now I can't export files on any account - it does not ask me to authorise using URL anymore.
When I try: claat export with doc ID, it doesn't work any more.
401 Unauthorized; {
"error": {
"code": 401,
"message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See
https://developers.google.com/identity/sign-in/web/devconsole-project.",
"errors": [
{
"message": "Invalid Credentials",
"domain": "global",
"reason": "authError",
"location": "Authorization",
"locationType": "header"
}
],
"status": "UNAUTHENTICATED"
}
}
I have no idea what it saved on my computer and where...
