auto_ts: How to change forecasted date range in auto_ts

Question

I am trying to forecast values using auto_ts library, the input i am passing is a date format which has first date of every month like 2021-11-01 whereas the forecasted values has a date range as last date of every month like 2021-11-30.

Is there a way to change the date range of predicted values to first date of every month ?

Thanks,
