No longer seems to work in Big Sur

Am not sure this is still being updated, but: after upgrading to Big Sur (currently running 11.1), running the 2.0.0 script results in no backups being deleted, despite being identified as falling into the cleanup criteria:

sandra@imac ~ % sudo tm-cleanup.sh -d 30 
2021-01-25-032852 will be deleted.
Total deleted: Zero KB
2021-01-31-163127 will be deleted.

2021-02-20-102921 will be deleted.

I suspect this is a result of a change in Big Sur tmutil command as described in this Apple Discussions thread (https://discussions.apple.com/thread/252036574):

The Big Sur syntax appears to have changed, but you need to specify the volume and the timestamp with -d and -t:
sudo tmutil delete -d /Volumes/Time\ Machine -t 2020-11-18-100936

Thanks!

This is the message that I'm getting now on 11.3.1:

sandra@imac ~ % sudo tm-cleanup.sh -d 30 
Password:
2021-01-25-032852 will be deleted.
Specify either a path or a mountpoint and timestamp
Usage: tmutil delete [-d backup_mount_point -t timestamp] [-p path]

I'm sure it's a matter of adding the correct switch/es to the tmutil command line within the code, but I don't know enough about tmutil and programming in general to do this myself.

Thanks, folks.

FWIW, I get the same error on Sonoma macOS 14.4.1 23E224 x86_64.
