Angular External js library calling Document.Ready

Using a 3rd party js library in my .net core asp angular app. The library applies it's logic in the $(document).ready method. So im having an issue where the libraries aren't applying correctly on a angular route change because the $(document).ready method doesn't fire.

I've referenced the external js library in my angular-cli scripts section.

I opened the 3rd party js file and added a method to it that calls the same logic that they are calling in the document ready. Im just struggling to find a way to call that method from my angular typescript component.

Any advice?
