The suggested help doesn't match the expected values, Would you consider changing this to

 choices=["key", "cred"], 
- help="Pass the Data_Type as Cred or Key", 
+ help="Pass the Data_Type as cred or key", 

Or

- choices=["key", "cred"], 
+ choices=["key", "cred", "Key", "Cred"], 
 help="Pass the Data_Type as Cred or Key",
