the intent action that will be used to launch your fulfillment activity when your app was chosen by the user to create the given credential, default to RegistryManager.ACTION_CREATE_CREDENTIAL when unspecified; when Credential Manager launches your fulfillment activity, it will build an intent with the given intentAction targeting your package, so this is useful when you need to define different fulfillment activities for different registries

the matcher wasm binary in bytes; the matcher will be interpreted and run in a safe and privacy-preserving sandbox upon an incoming request and it should output the qualified entries given the creationOptions and the request; an invalid matcher (e.g. one that fails wasm interpretation or causes exceptions) will mean that your application will never be surfaced to the user during creation
