How to get current text scale from UMG widget.

I’m using font measuring service to spawn invisible buttons under certain words in text widget.

TSharedRef<FSlateFontMeasure> FontMeasure = FSlateApplication::Get().GetRenderer()->GetFontMeasureService();
return FontMeasure->Measure(Text, Font, FontScale);

It works perfectly for DPI scale 1.0. I know text doesn’t scale linearly but is it a way to get current text scale and pass it to this function?
