Can't Find PhotonSecretKey on PlayFab's Photon add-on page.

Hi PlayFab Team,

I've followed this tutorial https://api.playfab.com/docs/tutorials/landing-tournaments/photon-unity on how to setup Photon add-on with PlayFab

I've finished these without problems.

- Setting up Photon Application

- Setting up Authentication

but i'm stuck in Setting up PlayFab title for Photon steps.

"Photon add-on page will allow to install Photon by specifying you Photon Realtime Application ID (1). Optionally, you may specify Chat Application Id. Once you install the add-on (3), Secret Key will be generated (2). Save it, as it will come in handy when configuring web-hooks:"

I added Realtime application ID and save settings, but no Secret Key generated from add-on page thus unable to configuring web-hooks to use in Photon

Title ID - 2F2C

App ID - 78bfc02e-83e9-49f0-8043-2e696df77aeb
