R3 button?

Gameplay
1

I just bought a steel series stratus controller for this game on iOS. It says r3 button to get into the hireling inventory but there is no r3 button on the joystick and it appears that I cannot bind this to other button in the menus

Is there a workaround?

Try pressing down on an analog stick

R3 button = press down on the right analog joystik
L3 button = press down on the left analog joystik
it is my PS3 joystik though

Tried that. It didn’t work. It’s really strange as it says l2 is to open my characters inventory but it’s actually the up direction on the 2nd analog stick. I am surprised that there is a controller remap section but all the buttons aren’t there
