comp importing script not working properly

hello guys, i am trying to make an extension to import project and add its comp to the timeline, however it only works well when i select the timeline or comp panel, if project panel is selected it import the project without adding its comp to my timeline.. any help will be appreciated , thanks..

here is my code 

function Generate() {

// Get a reference to the current project
var project = app.project;

// Specify the path to the project file containing the composition you want to import
var filePath = "C:/Users/mhmood/Documents/test.aep";

// Import the project file and get a reference to the imported project item
var importedProjectItem = project.importFile(new ImportOptions(File(filePath)));

// Get the first composition in the imported project
var importedComp = importedProjectItem.item(1);

// Create a new layer for the imported composition
var layer = app.project.activeItem.layers.add(importedComp);

// Set the in and out points of the layer to match the duration of the current composition
layer.startTime = project.activeItem.time;

}

$._ext = {
generateComComp: function() {
Generate();
}
};
