Just to let you know that Whisper Box doesn't work as intended with that module.
Attack Roll Check uses whispers to give the results to the DM, so the Whisper Box will get filled with messages during combat.

On top of that, the messages include information that the DM may not wish to share, such as the enemy's AC that the player will be able to see when checking their whisper history with the DM.
I'm also posting about the issue on Attack Roll Check's github: ElfFriend-DnD/foundryvtt-attack-roll-check-5e#8
