      org.freedesktop.impl.portal.AppChooser:
      @short_description: Interface for choosing an application

      This backend can be used by portal implementations that
      need to choose an application from a list of applications.

      This documentation describes version 2 of this interface.

              the application selection has involved user interaction, a new
              token should be generated by the portal implementation.
              Otherwise, this token may be the same as the one passed in
              @options.
