UiPath with Get IBM Lotus Notes Mail


I’m using Get IBM Lotus Notes Mail activity to retrieve email attachment. No problem with that. My question is: I created a Generic Windows Credential to store the email password and username in Windows Credential Manager. The password then i assign to SecurePassword of LotusNotes Mail activity. I also tried to store the password in GetPassword activity, but every time i run the process, it always prompt me for the email password. How to prevent this user interaction for entering password? Please help! thanks alot!!
