Cohort analysis

am created a cohort analysis but i need to remove rows with zero users
so how can i do this ?

using redash * Version: 8.0.0+b32245 (a16f551e)

The visualization doesn’t support this.

what about if i need to add row for total number for each column
am tried to add it using union but doesn’t working right
so any advise how to do that ?
