Confirm and Completed Icon in dashboard simillar

I am working on UX for the dashboard as we have booking progressing as our step for a booking system

one thing I'm not sure with this 'CONFIRMED' and 'COMPLETED'

Confirmed as the user is confirmed to collect the car

Completed in the last system as it's finished when the user returns the car

at the moment I'm using

So I feel there is some alter way to use confirmed icon rather than a green tick in confirm widget as I prefer it on the completed widget
