I had this for the Jan 2023 test! There's a little pause button you can use whenever you want on the test and when you resume your test you'll be given an additional minute to gather your thoughts/see where you left off! You cant write/work on your test while paused but it helped me when I felt overwhelmed or needed a stretch break to refocus. If you leave your room though let your proctor know and you'll have to rescan your room before you resume the test.
