Not getting interactivity immediately after loading the progress bar


I have tried different methods for progress bar as to get interactivity immediately after completing progress bar but none of them is giving expected output. kindly suggest me a solution for this.

I have loaded gltf model using GLTFLoader() by using Loading Manager. Using manager.onProgress function I am setting progress bar value as below but not getting interactivity after completing progress bar.
manager.onProgress =async function ( url, itemsLoaded, itemsTotal ) {

I have taken a counter variable and set its value upto 50% during manager.onProgress method and set it upto 100% after renderer function, but still I am getting interactivity after some time.

To the html progress tag didn’t gave “value” attribute so that the progress bar will be in indetermined state after loading giving 100 as value for value attribute.
