Annoying Notifications

Game launcher is a very huge step taken by Samsung for gamers.... it gives a lot of flexibility for gamers.. but that's going out of way now.... and this is hurting me...
   
       
       Updated game launcher in oneUI  really **bleep**.... The game launcher is now showing all app notifications when you are on games.... The previous versions of game launcher does it very good... It used to hide that app notifications and all other notifications... 
Please any developer take this as a serious issue and respond asap.... 
  And also performance modes... game mode is missing... where we used to have an option to record Screen
