Accessing when editing a page using elementor

  elementor, javascript, wordpress

can anyone help me figure out how to access when editing a page using the Elementor plugin?
We want to add a new image upload source from Brandfolder.

To do this, I added a button to the WordPress media library window and now, by clicking on it, we want to load pictures from another resource.
But the problem is even if I get the url and upload it to our host, but how can I insert this image into the window that Elementor opened?
