App Store Rejection - Purpose String (Camera)

Hi All,

I got the following rejection from App Store:
--------------------------------------------------
Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage

We noticed that your app requests the user’s consent to access their camera but does not clarify the use of the camera in the applicable purpose string.

Next Steps

Please revise the relevant purpose string in your app’s Info.plist file to specify why the app is requesting access to the user's camera. You can modify your app's Info.plist file using the property list editor in Xcode.
--------------------------------------------------

I am using Rhodes 7.1.0.beta1.

How can I specify that the applicable purpose string is set correctly in the Info.plist file?

Thanks a lot in advance for any help!
