How to change the order of the calendars?

How do I change the order of the calendars? Mike Richards2

asked a similar question a couple of years ago and never got an answer. I have many calendars, and honestly some have been there for so long that I don't know what they are. I would like to arrange my calendar list on the L sidebar either alphabetically or by color. How do I do that?

Thanks. I am on an older MacBook Air running 10.14.6
