Access an internal app that uses internal network using aws lambda function and zscaler

Hello, I would really appreciate any feedback from the community.

Let us assume the following:

  1. I have an internal web app running on an internal private network
  2. I can connect to that web app via two ways:
    • from the internal network without zscaler being on: before redirecting to the web app, zscaler pops up where the credentials are provided automatically in the HTTP GET request header, then authenticates, then get me the HTTP response in a JSON.
    • from any network (except for portals) with zcaler on (private access on), and then the same thing (mentioned in the point just before this) is repeated .

The question is: Let us say I have a Python code deployed via AWS Lambda. Is there a way to make the HTTP request using zscaler?

Thank you.
