How to show check background

Hi and thanks for your efforts.
I want to show the red background on check. it seems it does not add check square. I tried to recreate the board with a highlight option for check but that did not work either.

i found the solution

in aftermove function, i did something like this and that worked:

  if (this.game.in_check())
        this.board.set({
          check: true,
        });

by the way, I updated the chessground and it had some problems after the update I fixed that I can send pull request for these changes
