Issues with the floating bar given by chrome when i screen record in chrome from my react app

Hello I am expecting some kind of directions/solution here. I have a react web app which enable user to record screen and video. So i use JS getDisplayMedia() to get the screen recording. So for enhancing the experience I have a timer of 5 seconds shown before the recording starts . In this timer screen I had added a keydown listner to catch space and esc button. esc button will abandon the recording and space will pause the timer. Now I will come to my issue. When I use getDisplayMedia() the chrome will prompt a floating window asking what to share (window, tab, screen). and if I choose something there will be a floating bar shown in the bottom by chrome which says stop sharing or hide. If in the options I choose share my entire window then automatically the focus got to the floating bar below(stop sharing one) and my keydown listners won’t work until i click on the screen. So is there a way in which I can avoid the chrome focussing its floating bar. All other sharing options (screen, tab) it is not getting focussed.
