Hello! I want to allow users of my platform to connect their Zapier accounts in order for my platform to execute their zaps on their behalf. Basically, scenario is as follows:

• User gets on the platform and clicks “Connect your Zapier account”
• Oauth 2.0 magic happens and we get the token, that can be used to act on behalf of this user
• We are able to list zaps of this user on our platform and execute them using this token (e.g. from AI assistant that this user has created on our platform)

I’ve gone to https://zapier.com/developer-platform and set the oauth2.0 up, and I’m able to get the token which kinda works, however, I cannot access any APIs (e.g. GET https://api.zapier.com/v2/apps) as I get

{
    "errors":  
        {
            "status": "401",
            "code": "unauthenticated",
            "title": "User Not Authenticated",
            "detail": "User must be authenticated to access this resource. The provided access token may be invalid or expired.",
            "meta": {
                "source": "ZAPIER"
            }
        }
    ]
}

Could it be because my app is private? If so, is there a way to test things without making the app public?
