Final answer:
In Unified Service Desk, you can align a toolbar container hosted control using the Realign Window action with three parameters: 'left', 'top', and 'screen'. 'Left' and 'top' dictate the pixel distance from the edges of the screen, whereas 'screen' specifies which display to use.
Step-by-step explanation:
You want to configure a toolbar container hosted control and align it to a specific part of the screen in Unified Service Desk (USD) using the Realign Window action. The three parameters you can configure to achieve this are left, top, and screen.
The left parameter determines the distance in pixels from the left edge of the screen to where the window should be aligned. The top parameter is similar, specifying the distance in pixels from the top edge of the screen. Lastly, the screen parameter designates which screen the window will realign to, in scenarios where there are multiple displays.
Note that 'resolution' and 'client type' are not parameters used with the Realign Window action in USD.
