Share unpublished apps

Is it possible to share apps that are not published in the app store with non dev members of our team? I want them to be able to play around with the app features on their devices before we go live on the app store/google play store.

Would also love to know how folks do beta tests for their apps?

I am trying to figure out if capacitor/appflow is a good fit for my start up, any help on this would be appreciated!

We use Microsoft Appcenter for Dev and Android Prod Apps and for iOS Prod Apps we use TestFlight

For Android Google has internal testing tracks. You can use open, closed, or internal tracks.

Using the Play Console you can test your app with specific groups or open your test to Google Play users.
Testing your app gives you the opportunity to fix any technical or user experience issues with minimal user impact, so you can release the best version of your app on Google Play.

For Apple, you can use TestFlight

TestFlight makes it easy to invite users to test your apps and app clip experiences and collect valuable feedback before releasing your apps on the App Store.
