How to make app available for call inside an inner transaction?

I’m trying to call another app from the inner transaction of this app. App 269712329 has already been deployed to the blockchain. However, I’m getting logic eval error: unavailable App 269712329 because apparently it isn’t in the “applications array”. If that’s the case, how do I put it in the applications array and make it available? I would like it hardcoded with a specific int value, and not passed in through arguments.

itxn_begin
int appl
itxn_field TypeEnum
int 269712329
itxn_field ApplicationID
int NoOp
itxn_field OnCompletion
itxn_submit
