  This command will launch a terminal-based console for managing
  PSWorkItems. You can select items from the table which will
  populate the entry forms. You can then modify the work item and
  click Set-PSWorkItem, or you can mark the item as complete or
  remove it. To enter a new PSWorkItem, use Options - Clear Form.
  Enter your new item, selecting a category from the list, and
  click the Add New PSWorkItem button. You cannot set a progress
  value when creating a new work item. Use the category menu options
  to add, set, or remove a category.
 
  You can right-click a task in the table to show detailed information.
 
  You can also enter a different database path by entering the path in
  the Database field, or using Options - Open database. Use the
  Reset Form option to reset the form with your default settings.
 
  You cannot specify a PSWorkItem completion date using this tool.
 
  If you have difficulty seeing the cursor in text fields, and you are
  running in Windows Terminal, you might try changing the cursor in
  your Windows Terminal profile setting. The TUI color scheme is
  also influenced by the Windows Terminal color scheme. You may also
  have to adjust the zoom level in Windows Terminal to see the entire
  form.
