How do you expand the language menu when the preloader hides?

The language menu is collapsed on load, but I’m not sure how to make it expand once the website loads and the preloader hides.

Here is my code:
import { session } from “wix-storage” ;
let status = session . getItem ( “status” );
$w . onReady (() => {
if ( status ){
$w ( “#columnStrip2” ). collapse ();
} else {
waitForLoading ();
session . setItem ( “status” , “revisit” );
}
})

export function button6_onClick () {
$w ( ‘#columnStrip2’ ). show ();
waitForLoading ();
}

function waitForLoading () {
setTimeout (() => {
$w ( ‘#columnStrip2’ ). hide ( ‘FadeOut’ );
}, 1500 );
}

#columnStrip2 is the preloader and the ID for the language menu is #languageSelector8
