P.S.: Almost forgetting, these are the things that need to be added:
a) be able to bypass the column upwards block (cells can’t be move upwards, the sheet gives an error).
b) if the user’s “name” isn’t already in the sheet, then add it at the bottom; if there is, leave only the latest reply.
c) every day, remove the replies of the day before.
d) remove empty rows and move upwards the bottom ones, to compact remaining cells in less space.
e) group all rows by same “department” variable, to organize the sheet.
