First of all, we need to open the setting function of the desktop. More setting function keys can be found in the drop-down function. Click Open. Because we allow an application to open the floating window function, we must give them this right first, so we need to find the appropriate management function after opening it. Then find the application we want to set in the application area, and Bian Xiao will choose any application for demonstration. After entering the settings of this application, click the personal permission settings, and we can see the function of the floating window. Click it to open it.
