'AnyKey' doesn't seem to register.

Hi, I’m trying to make a help screen that appears when user is idle. My BP is below. It works fine for mouse input, but doesn’t seem to be affected by keyboard input (‘InputAction AnyKey’ is an Action Mapping combo of mouse movement, clicks and AnyKey)

Am I missing something? I’m in UE 4.22.1

Hi. Did you manage to solve it? I just got into this issue right now. If you have a solution it will be really helpful to share. Thank you in advance
