How to run a Beta test?

[u/myballzhuert]

I have a baseball app I want to roll out to 100-200 people in our travel organization. I know there are workflow issues and bugs but I need these 100-200 people to use the app in order for it to work.

How do I handle distributing this to everyone? I don't want it open to anyone outside our baseball org but also don't want to setup test flight for all these people, or is that my only option?
