Could a "fileRemoveAll"/"fileEmpty" event be created?

With this, if a user uploads multiple files - and then removes one, the target button becomes disabled.

I'd like to only disable the target button when the field becomes empty again.

Resources (screenshots, code snippets etc.)

let fileUploadInput = document.getElementById('dnd-multiple-files');
fileUploadInput.addEventListener('fileAdd.mdb.fileUpload', (e) => {
    postbtns.classList.remove('disabled');
});
fileUploadInput.addEventListener('fileRemove.mdb.fileUpload', (e) => {
    postbtns.classList.add('disabled');
});
