Distributing on appstore connect unsing the new Testflight Internal Only


I read the documentation but I am not able to grasp how I can deploy Testflight Internal only build on appstore connect.

I’m able to do it from Xcode and am looking for a way to do it through Bitrise.

Does someone know if this is possible through an existing step or the command line parameter that would let us do that ?

Thank you in advance for your help :pray:
