Change the style of a text inside a disabled UMG button

If I create a new text widget and place it as a child of a button widget, when the button is disabled the text is greyed out, but I can’t choose its colour.

The tint colour only affects the button material and not the text and the text colour is taken into account only to be greyed out anyway.

How can I force the colour the text should have when the button is disabled?
