Focus Mode issue

[NoobMaster_69]

I always use focus mode when I do my work for long hours. But few days later (I was not using focus mode) The icon disappeared! I checked my edit buttons options, but nothing to be found.. 

I use a Galaxy Tab A7 with One UI 3.1

Please leave a recommendation to fix this...
