I 'am able to build and run the PoseLandmarker example in xcode, but I am trying to create a library wrapper to be used in B4X platform which is a platform to build Android and iOS apps using Basic syntax programming language, I am facing an issue when using the following code
`- (MPPPoseLandmarker *)createOptions: (NSString *)tasfilePath :(float)minPoseDetectionConfidence :(float)minPosePresenceConfidence :(float)minTrackingConfidence{
NSError *optionsError = nil;
NSString *modelPath = [[NSBundle mainBundle] pathForResource:tasfilePath ofType:@"task"];

if (!modelPath) {
    NSLog(@"Error: .task file not found in DirAssets.");
} else {
    NSLog(@"Model path: %@", modelPath);
}


MPPPoseLandmarkerOptions *options = [[MPPPoseLandmarkerOptions alloc] init];
options.baseOptions.modelAssetPath = modelPath;
options.baseOptions.delegate = 0;
options.runningMode = MPPRunningModeImage;
options.minPoseDetectionConfidence = minPoseDetectionConfidence;
options.minPosePresenceConfidence = minPosePresenceConfidence;
options.minTrackingConfidence = minTrackingConfidence;
options.shouldOutputSegmentationMasks = false;
options.numPoses = 1;

NSLog(@"options created successfully");

MPPPoseLandmarker *landmarker = [[MPPPoseLandmarker alloc] initWithOptions:options error:&optionsError];

error:&optionsError];
if (optionsError){
NSLog(@"optionsError: %@", optionsError.localizedDescription);
}
return landmarker;
}`

The library wrapper compiles just fine when I use it in B4X and the app runs, the problem is that I see an error when initializing the landmarker with the landmarkeroptions, the errors i 'am seeing is the following

NOT_FOUND: ValidatedGraphConfig Initialization failed.

No registered object with name: mediapipe::tasks::vision::pose_landmarker::PoseLandmarkerGraph; Unable to find Calculator "mediapipe.tasks.vision.pose_landmarker.PoseLandmarkerGraph"

The application doesn't crash but it is obvious something is not right, I am using MediaPipeTasksVision.framework version 0.10.20, I also tried version 0.10.14 but I see the same issue, I have both frameworks MediaPipeTasksCommon.framework and MediaPipeTasks.framework referenced in my library wrapper project and i know the task file is being found as I can see the logs the name of the .task file

Model path: /private/var/containers/Bundle/Application/B773963F-D4D6-438E-BAF6-FA0911F44C6F/tros.ai.app/pose_landmarker_heavy.task

I have been at this for days and can not figure out what I must be missing, hopefully I can get some help here from the experts, in advance thanks for the help.
