Photon demo particle doesn't work in 4.18 UE4

Hi,

I tried to run demo particle following the instructions below but it doesn't work.
https://doc.photonengine.com/en-us/onpremise/current/getting-started/unreal-engine

So this is what I have done so far:
1. I already have UE4 SDK 4.18
2. I downloaded photon sdk for Android
3. I followed step 4 and copied android sdk to specific folder within source/photon/lib folder
4. I opened context menu by right click on ./PhotonDemoParticle.uproject and chose "Generate Visual Studio project files
5. I then tried to build Games/PhotonDemoParticle

And I'm getting the error below
