Hi Praveen,

yes you can customize the popup by overriding popup CSS 

for example, you can increase  width and height and also auto X and Y 

Here just I am one example maybe you will get an idea 

.popup-dialog.custom-style2 {
    min-width: 70vw;
    overflow-y: auto;
    padding-bottom: var(--space-l);
    
   
}
