FC25 Keeps Asking for 'RMB', Not X

I recently started playing FC25 through Xbox PC Game Pass.
I'm playing on both my PC and a handheld PC (ROG Ally). I enjoy the Player Career Mode, but when it comes to Match Objectives during games, I want to activate the Enhance Objective. However, the game only tells me to “Hold RMB.” I understand it might not work easily on the ROG Ally, but even when I play on my PC using an Xbox controller, holding the Right Mouse Button doesn’t work.

I've searched online but haven’t found anyone else mentioning this issue, which is frustrating. On other console images, the prompt says to “Hold X” instead. I wish the game would prompt me to hold the “X” button instead of “RMB.”

Is there any way to change this in the settings? Please help me. I’m really stuck.
