Make a Discord bot in Python -- 2

Hey, looking to get a bot made to keep track of a few things and update a google spreadsheet. The link to the sheet is below. Basically what I'm looking for is to add the name of the user to the "B" column when they join, along with the date they joined in column "E". I also want to be able to delete their row from the sheet if they leave, and update their username on the sheet if they update their name in discord.

Just to make sure, I do get the source code for this after it's done?

Thanks!
