MailWatch / MailScanner GeoLite2 Activation

Hello,

Hope everyone one is well,

I am trying to add GeoLite2 to MailWatch, i have the licence key but the instructions i have found tell me to add the licence to the conf.php file, but i cannot find this file anywhere, can someone please point me in the right direction. or give me some instructions on how to get this working.

Mailwatch and Mailscanner are working correctly no issues with emails so far.
all items install from cyberpanel GUI.

Hope to hear from you soon.
