Delay a script

Hi,

First of all, thank you for the great plugin!

I want to use a phonecall script, the script does its job but because it loads to early the rest of the webpage is not loading. I’m using the Avada theme.

The script is:
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
window.location = “tel:1884”;
}

I’ve placed it in (end of the body tag).

Is it possible to delay the script?
Custom scripts are new to me so hope you can help me ??

Thank you and have a nice day.
