MAUI Best method of setting the configuration per environment

So I have a MAUI app with a lifecycle config of the following

1. Dev machine config
2. Dev environment config (early preview)
3. Staging (UAT) config
4. Production (Live) config

Question: How do I configure the app as it switches between stages

How do I know the app is in e.g.

• Android internal testing and the config should point to the dev environment
• Android Open testing and the config should point to the staging environment
• Android Production and the config should point to the Production environment
• IOS internal testing and the config should point to the dev environment
• IOS Open testing and the config should point to the staging environment
• IOS Production and the config should point to the Production environment

Cheers all
