Hi Pragathi,
You are not really specific in your question.
One way to do it would be to use a microflow as your data source.
In this microflow create two date time variables: the first to hold the begin of the previous week (e.g. calculated as addWeeks([%BeginOfCurrentWeek%], -1)) and one to calculate the end of the previous week addWeeks([%EndOfCurrentWeek%], -1).
You can subsequently use these two variables in a x-path retrieve resulting in the list of objects within those boundaries.
