If you use elasticsearch 8.x you have to set the following configuration for elasticserach:
action.destructive_requires_name: false
Otherwise there is an error and the DataHub configuration could not be deleted.
=> there are probably several other problems without this setting
see: https://codezup.com/solved-wildcard-expressions-or-all-indices-are-not-allowed-elasticsearch/
I think it would be nice to add this to the documentation.
ps. thanks for your work / this plugin
