Can someone please run through the steps to set up a workflow to send an 7 day overdue email from a sharepoint document library
I have a document library that has a column for 'response date' (Date) and a column 'review confirmed by' (people picker).

i want a flow that
1. recurrence - I have done
2. get files (properties only) This is the only one i can find for document library) - i have this and added filter query i used filter query ResponseDate eq '@{addDays(utcNow(), -7, 'dd/MM/yyyy')}'
3. if column response date is 7 days overdue and review confirmed by column is blank (what do i do here)
4. send an email- i cant get this to work even with a apply to each

Please help
thanks
