Subtitles built-In system and background blur of Ui

Hi everyone,
I use in my project the built-in susbtiles system (to write sentences/ideas said by the character (waves files)) of UE but when an Ui with background blur is launched , the subtitles are behind the Ui and so are blured. Have you any ideas to display subtitles foreground ? Thanks !

I found the solution by buying the plugin “Native Subtitles into UMG” in the unreal marketplace. It works pretty well !
