A few years ago I created a second boot partition on a MacBook, called "BootOS". I would like to delete this partition and merge the space back into the remaining partition.
I have found a question/answer that describes how to do this on El Capitan, but the output from diskutils list
on Catalina looks sufficiently different for me to ask again.
Can anyone suggest suggest how I should go about this?

Disk Utility.app in the /Applications/Utilities/ folder would be my recommendation. That's generally the easiest/safest way to make changes to partitions.
