appid for forwarder-creation?

[blaizx]

"You'll need to add thees arguments to the forwarder:

--host - Mac address of your PC (you could find it in /switch/Moonlight-Switch/settings.json)
--appid - ID of the app to launch
--appname - The name of the app without any spacings
example: --host=a2:34:de:ad:12:3b --appid=1233211234 --appname=Steam"

mac-adresse is easy
appname is the name I gave the Game/App in GeforceExperience/Shield (For Example "returnofthetentacle")
but how I get the appid from?

You can add game to your favourites, than open /switch/Moonlight-Switch/settings.json and find this game in favourites list, it will contain the same appid you need for forwarder

appname is just text you'd like to see in the app, so it could be simply anything (without any spacings)
