when I check the data capacity, I found that the data is almost full and need to delete some data.
Confirmed that it is the workflow entity that is running tight on capacity.
So I decided to delete some workflows and delete the ones I created for testing.
However, it is not possible to filter infrequently used workflows created for testing or workflows with old last use dates.
Since filtering is not possible we want each record to reflect the frequency of use and the data of the last use date.
Therefore, we can filter the workflow we want to delete.
