Subtitle Background

Hello everybody, Is it possible to add a background to subtitle? I mean, there are many different situations in the game that player can’t see subtitle because either font and game environment are white.
I use built-in subtitle ability that taught in [this][1] page.

really anyone doesn’t know how can I achieve this?

I tried with UMGs but the subtitles are always behind any UMG it seems. :frowning:

Extremely frustrating. I transcribed 100s of audio files to ensure my game is accessible and it looks now like I get to redo everything and write my own UMG blueprint for managing the subtitles.
