The dot-dash broken lines in the drawings show a display screen or portion thereof and form no part of the claimed design. The remaining broken lines in the drawings, including all text, and icons, show portions of the graphical user interface that form no part of the claimed design. The solid grey areas in FIGS. 1-3 and 7-9 indicate a contrast in appearance and are part of the claim.

The appearance of the transitional image sequentially transitions between the views of FIGS. 1-3, FIGS. 4-6, FIGS. 7-9, and FIGS. 10-12. The process or period in which an image transitions to another forms no part of the claimed design.
