How to binding 'I' key to open inventory grid?


I create inventory panel by myself not use defaulit 'Classic Schema Full Layout', everything is okay but I found the hotkey is not working for me.

I checked by my input manager like this:


And I have been compared between demo and my panel, I know I lost some important informations, but there has too many properties...
So could you give me a little bit tips for this question?
Thank you so much...

This is my inventory inspector:

You can open/close panel with input using the DisplayPanelManagerHandler component.
By default 'I' (OpenClosePanel) is linked to open/close the MainMenuPanel set within the DisplayPanelManager component.
But you can change it to open a specific panel by using it's name if you want.
I hope that helps
