I typed my comment above on my mobile keyboard. I’m just using the standard Google keyboard on my Pixel, nothing fancy. Em and en dash are available by holding on the hyphen, and the ellipsis is available by holding on the period (annoyingly, only when on the numbers/symbols page).
If Ukraine wants a breather they can agree to it knowing they need to stay alert for the Russians to break it.
If Ukraine doesn’t want to play that game, they can just say “we’ll agree to a ceasefire when you leave Ukraine permanently” and carry on.
