@Divyasri - You can generate test case documents in Word or Excel, but even better is to upload to Azure DevOps (formerly called TFS). That way you can track pass/fail status, perform multiple test runs, etc.
This video shows uploading test cases to DevOps, including how to attach a diagram (e.g. a wireframe or other image) to a specific test step. It's a little dated, so some of the names have changed, but the functionality is the same:

This article describes uploading to DevOps in general:

CaseComplete comes with built-in test case reports, but if you want to show diagrams associated with test steps, you can create a custom report (see sample report attached here):

Finally, the test scenario feature is described in detail starting on page 49 of the tutorial (access via File / Help in CaseComplete.
Take a look and let me know if you have any questions.
