How to use expo build:ios with multiple release channel?

I have an iOS app made with expo SDK 36 and I use Debian 11.

For this reason, I use:

  • expo build:ios for building the .ipa in the expo CI server. <= run from linux
  • expo upload:ios for publishing my application the first time for test flight. <= run from a distance macOS 10.15.4 Darwin 19.4.0 with xcode 11.5 over SSH

This work fine but I have 3 channels and I can’t select which release I am releasing for testflight, I have noticed a --config option for this command but I am not sure how to use it.

How can I upload a specific channel last release to the application store ?
