Can't find homebridge v2 "view configuration data"
## Verify the following before opening an trouble issue

I'm probably just missing something obvious here, but it could also point out a potential way in which the documentation may be misunderstood.

**Go over all the following points, and put an `x` in all the boxes that apply.
If you're unsure about any of these, don't hesitate to ask. We're here to help!**

-  [X] That _OAuth_ is Enabled for the SmartApp under the IDE.
-  [X] The SmartApp and Device Handler are using the latest code available.
-  [X] That Both the SmartApps and Device Handlers have been _Published for You_ in the IDE.

## About Your Setup
-  How many devices are detected?: all of them just fine.
-  Mobile App Version(Not required):
-  SmartApp Version: 2.3.3
-  Device Handler Version:
-  Homebridge Version: 4.50
-  NodeJS Version: 12.14.0

## Expected Behavior
**Tell us what you think should be happening**
I was following your installation instructions and everything was fine up until I edited config.json to add the homebridge-smartthings-v2 configuration there.  The instructions say:

app_url & app_id & access_token Required To get this information, open the SmartThings HomebridgeV2 SmartApp in your SmartThings Classic Mobile App, and tap on View Configuration Data for Homebridge Notice: The app_url in the example will be different for you.

I would expect that opening the Smartthings iOS app on my phone and tapping on "Smart Apps", then "Homebridge v2", would show me the "View Configuration Data for Homebridge", but I don't see any such thing.

## Current Behavior
**What happens instead of the expected behavior?**
I have a Smartthings v3 hub.  I tried both the latest Smartthings iOS app and the "Smartthings Classic" version of the app, I don't see any "View Configuration data for Homebridge".  I have looked through many, if not all, of the screens and menus.  I just don't see this.


## Steps to Reproduce (for bugs)
**Provide a link to a live example, or an unambiguous set of steps to reproduce this bug. Include code to reproduce, if relevant**

1.Open Smartthings iOS app.
2.Click on Smart Apps

I can't complete my config.json configuration.
