Preload Concated JS File

[Jayp2002]

I am using angular extension in my angular 14 app, is there anyway to preload the requested JS file once a user has successfully logged in?
At the moment user logs in and then clicks on a tab to load , but this takes around 11 seconds to load the JS file, file size being request is 7.3MB as the whole application is wrapped as a web component.

<ui-app *axLazyElement="url"></ui-app>

Is there anyway to improve the load time for the requested JS file?
