Make chart time slot not clickable when accessibility servie is enabled 

after discuss with Shuan & Peggy, we will make the chat view is not
clickable since accessibility service is enabled for talkback, switch
access and voice access, since some gestures are conflict with our
design (double click to show all contents is conflict with a11y behavior)
