Unity catalog; how to remove tags completely?

[Synasenn]

Hi,

We are rolling out Unity in our organization and while playing around I had set some tags on a test catalog.
After removing this catalog, the tag keys I used are still present in our Unity environment and I am unable to find where they are stored to delete them.

- There are no catalogs that use these tags
- No tags are present in any of the tables in  system.information_schema

Can anyone point me in the right direction?
Right now I am stuck with these;

Hello many thanks for the question, if the tags were not removed before removing the catalog, this data will be retained in the metadata for 30 days, this is part of the retention policy, once this 30 days pass you should no longer see the tags as option.

As suggestion you should remove this tags before dropping the catalog.

Thanks! I will take that to heart and include it on our internal wiki
