The patent file contains at least one drawing executed in color. Copies of this patent with color drawing(s) will be provided by the Office upon request and payment of the necessary fee.

FIG. 1 is a view of a first image in a first embodiment of a display screen or portion thereof with transitional graphical user interface showing our new design;
