Jitsi Meet Capture Screen Width

Hi Team

I would like to change some icon when the Width of the screen is <=1024

for that I have written below code to try and capture screen width.

_iconReplace(){
        
        let iconShow
        if(screen.width<=1024){
            iconShow =IconTileViewOverflow;
        }else{
            iconShow =IconTileView;
        }
    return iconShow
    }

When I reduce the screen Size using mouse to reduce the screen the above code is not hitting the IF condition,
If I use the responsive tool from Developer tool then this works fine.

How could I capture the Screen width when I reduce the width manually using mouse ?

Any thoughts ??

How are you capturing the screen size in your code?
