2.1.5 [Webdriver:2018] Section 10.7 Resizing and Positioning Windows

The specification states:

 6.5 List of Endpoints
  
     The following table of endpoints lists the method and URI template for each endpoint 
     node command. Extension commands are implicitly appended to this table.
  
     Method | URI Template                            | Command
     --------------------------------------------------------------------
     ...    |                                         |
     --------------------------------------------------------------------
     POST   | /session/{session id}/window/minimize   | Minimize Window

     --------------------------------------------------------------------
     ...    |                                         |
  
 10.7 Resizing and Positioning Windows
  
     WebDriver provides commands for interacting with the operating system window 
     containing the current top-level browsing context. Because different operating 
     systems’ window managers provide different abilities, not all of the commands in this 
     section can be supported by all remote ends. Support for these commands is determined 
     by the window dimensioning/positioning capability. Where a command is not supported, 
     an unsupported operation error is returned.
