Open Disk Utility

Click on the View button and choose "Show all Devices"

You should see your WD Passport listed in the list, likely with some volume name indented below it.

Select the drive in the list (leftmost entry for the drive).

Click the Erase button and choose a desired format. macOS Extended (Journaled) is probably the best choice.

Do you need to use the drive on a Windows computer to share files? If so, use ExFAT.
