Blocking via Biometric Management in Android eMclient

In the Outlook application via Cell Phone, I can have the biometric lock at the start of the app, where I can only access the Outlook email manager application with my finger. However, I did not find this in the eMclient manager. Does it exist? If it does exist, where is it so I can activate it and only be able to access the application with my fingerprint? If it does not exist yet, is it possible to implement it soon???

There is a current eM Client suggestion link below to add biometric login support in the mobile app via the Sleekplan share ideas and voting page. Suggest you vote for that.
