I'm new in joomla 4, I used to use joomla 2.5 and to open popup using Javacript I use this

JHTML::_('behavior.modal');
function editItem(idItem)
{
   SqueezeBox.open('index.php?option=com_transit&task=dev.edit&tmpl=component&id='+idItem, {handler: 'iframe', size: {x: 550, y: 350}});
}

Now with Joomla 4 SqueezeBox is unknown and it throw an error

I find some solution to open the popup, but here the URL is not always the same so I have to open a popup(modal) with differant url

Thank you
