Need guidance in polling within Intellij plugin

Hi,

We are working on a plugin in which we are constantly calling our web API and based on the response of the API we are forming a tree view in the tool window, we are making the api call on pooledThread and then forming the UI. Whenever the UI gets recreated [Polling] there as slight freeze of 1 sec in the IDE. We are not able to solve this issue, could you please tell us the right approach of doing this or let us know if there is any mechanism in Intellij which we can reuse. 

Note: we are forming the UI using .invokeLater Method because it gives the below error otherwise

polling = executorService.scheduleWithFixedDelay(() -> {
    if (!activeApiCall) {
        Runnable runnable = this::runCallApi;
        application.executeOnPooledThread(runnable);
    }
}, 0, POLLING_INTERVAL_SECONDS, TimeUnit.SECONDS);

ApplicationManager.getApplication().invokeLater(Window.formUI(apiResponse));

Thanks

Vikram
