Is there a Chromecast develop/debug APP_ID

Is there a Chromecast develop/debug APP_ID

I live in Italy and I cannot buy atm a chromecast to develop with.
I managed to emulate chromecast in my chrome browser thanks to leapcast
but I still cannot develop with it because afik I need a whitelisted
APP_ID.
Is there a already whitelisted APP_ID used only for debug/develop mode
that I can use in this "special" case?
