Removing widget input after box trigger event

Hi! Let me quickly explain what is happening in the game. Basically we can inspect objects by pressing a key, which displays a text description at the bottom of the screen (just like in the old survival horror games). When we enter the bathroom, we can hear a woman crying behind one of the stalls. We can inspect the stall, the characters comments about the voice being creepy and blahblahblah. However, after grabbing a key, the crying stops (the key is located inside a box trigger that stops it). I’m trying to disable this said text description widget after grabbing the key, because it would make no sense for the character to keep commenting about that voice that isn’t there anymore.

I tried disabling the input inside the level blueprint by creating a reference to the widget, but it didn’t work. Here’s a screenshot of the widget if that can be of any help
