After you installed the file manager the first thing you probably want is to open its dialog to select and show some file or files and then use them in your app. This is the most popular way to use file manager.

Retrieving Flmngr API differs depending on integration, but they all will use one Flmngr.open({params}) method to open the file manager.

This example will print the selected image into the console of your browser (press F12 to open it).

files array will guaranteed have only one item because isMultiple option is set to false.

acceptExtensions will limit acceptable extensions (the file manager will filter non-image files from the listing and allow user to pick images only), so this method will return URL of some image in onFinish callback.

You can do anything you want with this file: print it, save or add HTML image elements to your editor. Just replace console.log() with your code.
