For loading functionality:
1.  Add the "₲⁞FL - Sender" on the page you are going to be adding inside the frame.

2. Add the "₲⁞FL - Receiver" on the page you are displaying the iFrame.

3. Trigger an event when the "loaded" status of the RECEIVER is true or false. That's it!

NOTE: You must enable iFrame access in your app's settings. If you do not allow iFrame access, you may only work within the scope of your own app.

**THIS IS ONLY TEMPORARY. I may add CORS features if anyone need this ability.
