Legacy Nest access

For Nest Protect device integration you can use the Legacy Nest tab. To gain access you need to provide two fields to the app. The fields are IssuTokenURI that will request a token from Google NEST and a Cookie that is associated with that Token. The two fields will be used by the app to mimic a browser session to NEST like you are being logged on to NEST.

The instructions below will set up this session in incognito mode of Chrome. When you are ready and auth is verified with the app, DO NOT LOGOUT of the session, just close the tab/browser.

If you do logout, the session will cease to exist in both the app as in the browser.
