Lottie Animation (Json file) loads with delay after preloader completes on wordpress site

I’m using elementor and preloader plus plugin from wordpress on my site but when the site loads, the preloader closes before the complete site load. I’ve designed a lottie file(Json File) which loads after the preloader closes even though the json file is not on lazy load hampering the essence of website.
