Contact the app developer running the TestFlight.

Nobody around this discussion can provide TestFlight codes, nor provide access to third-party or Apple apps.

TestFlight is a way for app developers to get help testing their maybe-not-completely-ready-to-use apps.

TestFlight is not a try-before-you-buy mechanism for apps.

If helping to debug a potentially-buggy app is interesting to you, contact the app vendor you are seeking to assist with debugging and testing, and inquire if they’re currently running a beta for the app. The app vendor created the app, and—if there is a beta, and if the beta is using TestFlight—is managing the beta and any TestFlight codes.

You won’t get one from here.

You need to contact whoever is offering the application you are trying to get.
