No fast way to clear existing sheet, no way to delete old sheets – Scribble Together Whiteboard Review

My family is trying to use this app as a “white board” for a hospital patient who isn’t able to speak or text right now due recent procedures. Because visiting hours are so limited, we thought the virtual whiteboard would help supporting family members to know the patient’s needs from afar and ensure the nursing staff are following through. However, we can’t figure out how to “erase all” on an existing sheet, or how to delete old sheets?
