Using Reqnroll for Avalonia User Journey Tests - Setup Guidance

[vmWarp15]

I'm trying to set up Reqnroll (successor to SpecFlow) to write user journey tests for my Avalonia application. My goal is to test complete user workflows through feature files rather than individual unit tests.
I'm running into platform initialization issues when trying to integrate Reqnroll step definitions with Avalonia's headless testing framework. Standard [AvaloniaTest] methods work fine, but Reqnroll binding methods fail with platform service errors.
Has anyone successfully integrated Reqnroll with Avalonia for UI testing? Looking for guidance on:

Proper initialization approach for BDD scenarios
Whether there are known compatibility issues
Alternative approaches for user journey testing in Avalonia

Any pointers or examples would be greatly appreciated!
