Widget instance with binding for options menue

Hi, I’m trying to make a modular options menu. So, I created a widget with a button and text, and dragged and dropped it into the Options Menu widget. I also made the Button text accessible from the instance. But I need the binding option to change the text according to the chosen setting.

Here’s the Button:

And the options menu where I need the Bind dropdown:

How can I expose the Bind dropdown for the text of my widget Blueprint?

Thanks
