Rebind Quick Settings Overlay Button

hey fellas! allow me to start off by saying i apologise if this has already been asked, i've spent several hours googling a solution for what i'm looking for and i just cannot seem to find an answer for it. this also goes for in here, but i could have missed it. i'm sorry again if i managed to i have bazzite installed on my legion go. when i play certain games (assassin's creed syndicate, for example) i sometimes wish to access the ingame pause menu of said game. however, when i press the legion r button (which serves as the 'start' button for most games) it instead insists on opening the right-hand side overlay menu (pictured). it may be important to note this is through steam remote play, so this could be altering the behaviour somewhat this seems like something that should be an extremely simple fix and i imagine it would be, but it makes it no less frustrating when it comes to the amount of time i've wasted chasing dead ends finding a fix to this. on top of that i've somehow managed to fry the controller settings menu to the extent it is now blank and i'm unable to change any settings in there at all anymore. i may have to open a separate ticket for that too! but one step at a time to get to the point, what i want to do is remap the overlay menu to instead be opened via another button. or if that is not possible to do at all, then disabling it from being opened by any button in general would be fine. i'm hoping there is a solution to this issue i've ran into. thank you in advance!
