How to use Bumper buttons in Unreal Engine development

I tried running the VR template project on Magic Leap 2 while following the link below.

In the VR template project, there is logic to shoot a gun, so I want to treat the Bumper Button as an input in
Content/VRTemplate/Input/IMC_Weapon_Right, but I can't select the Bumper Button.

How do I use the Bumper Button in Unreal Engine development?

My development environment is as follows:
ML C SDK version: 1.7.0
Unreal Engine version: 5.3(Source code build)
Unreal Plugin version: 1.4.0

Hey sentomo,

Welcome to the Magic Leap Developer Forums!

In Unreal, the bumper button on the controller is named "Shoulder"
To set this up, please navigate to Content/VRTemplate/Input/IMC_Weapon_Right to begin editing the controller mappings.

Under Mappings->IA_Shoot_Right, you should see a drop down that allows you to select a button to map this action to.

From that dropdown, you will want to select Magic Leap Controller->Magic Leap (R) Shoulder

Please let me know if this works for you!
