new OpenModalJs(

  {
    openOnInit: false,
    openClass: "open",
    overlayClass: "modal-overlay",
    closeButtonClass: "modal-close",
  }, 
  {
    onOpening: () => {},
    onOpened: () => {},
    onClosing: () => {},
    onClosed: () => {},
  }
)

const modal = new OpenModalJs('some-element-id')

//Open the modal
modal.openModal()
//or
modal.isOpen = true

//Close modal
modal.closeModal()
//or
modal.isOpen = false

Listen for events

const handler = (event) => {
  const modal = event.detail; //<- access the modal object
    
  if(modal.modalId === 'some-element-id'){
    //Do something
  }
}

document.addEventListener('opening:modal', handler) // .open css class added ("transitionstart")
document.addEventListener('opened:modal', handler) // opening css transition end or canceled ("transitionend" or "transitioncancel")
document.addEventListener('closing:modal', handler) // .open css class removed ("transitionstart")
document.addEventListener('closed:modal', handler) // closing css transition end ("transitionend" or "transitioncancel")
