What is the best way to expand a Modal in Bootstrap 4?

Initially, I am facing an issue with Object-Oriented Programming in javascript, and my understanding of it is quite limited. However, I urgently need to resolve this problem...

Currently, I am attempting to utilize a library designed for Bootstrap 3 within Bootstrap 4: https://github.com/nakupanda/bootstrap3-dialog

The error message I encounter is: "Cannot call a class as a function"

Upon reviewing the code, I have made the following observations:

1 - The function classCallCheck is responsible for triggering the error. It appears that it enforces the usage of "new" to instantiate an object and prohibits invoking it as a regular function;

2 - The function createClass is used to construct classes, therefore, the class structure in Bootstrap 4 does not adhere to conventional definitions.

3 - Another function named inherits indicates that the inheritance process is also unconventional.

4 - The library includes the following code snippet to extend the Bootstrap Modal:

var BootstrapDialogModal = function (element, options) {
    Modal.call(this, element, options);
};

However, the error "Cannot call a class as a function" is triggered by Modal.call

I believe the underlying issue lies in BootstrapDialogModal inheriting from Modal based on the inheritance conditions set by Bootstrap 3, which are no longer applicable under Bootstrap 4.

Here's a link to the jsfiddle for reference: http://jsfiddle.net/g6nrnvwu/

If anyone has insights on how to address this code issue, your assistance would be greatly appreciated.

Thank you.

While this may not be a direct answer, here's an example that could potentially assist you. I have created a custom class for dynamically handling modals by inserting their markup on the fly. Although it is not based on BS4, you might find it useful as a reference.
