Sequence animations on hololens

Hi,

I can't seem to get an animation to play on hololens 2.

I created the sequence in Illustrate 6.1 and used the code:

$scope.app.playModelStepPvz("Roller Handle","Figure 1","roller_handle",1,true) 

//////////////
//definition of the function
$scope.app.playModelStepPvz = function (pvz,sequence,modelName,step_number,play) {
 
//pvz file
//sequnece -sequnece name e.g. TestFigure1 - as shown in UI
//modelName - model name e.g. model-1 widget
//step_number - set this number to current step
//play true/false execute play for the model
 
 $scope.$applyAsync(()=>{$scope.setWidgetProp(modelName, 'src', '');}); 
 $timeout(function () {
 $scope.$applyAsync(()=>{$scope.setWidgetProp(modelName, 'src', 'app/resources/Uploaded/'+pvz +'.pvz');});
 },50);
 $timeout(function () {
 $scope.$applyAsync(()=>{$scope.setWidgetProp(modelName, 'sequence', '');}); 
 },50);
 $timeout(function () {
 $scope.$applyAsync(()=>{$scope.setWidgetProp(modelName, 'sequence', 'app/resources/Uploaded/l-Creo 3D - '+sequence +'.pvi');}); 
 },50);
 $timeout(function () { 
 $scope.$applyAsync(()=>{$scope.setWidgetProp(modelName, 'currentStep', parseInt(step_number));});
 if(play) //check if play should be applyed
 $timeout(function () {angular.element(document.getElementById(modelName)).scope().play(); }, 100)
 //angular.element(document.getElementById(modelName)).scope().play(); }, 100);
 }
 , 500);
};
