I am unable to add custom fields to Serenity Reports (using the latest version)

Question

I am trying to add Custom Fields to Serenity report mentioned in this link: https://serenity-bdd.github.io/theserenitybook/latest/extended-reports.html

Tried by adding ApplicationVersion information in serenity properties file in this format :

report.customfields.ApplicationVersion = 1.2.3

The serenity version that I use is 2.0.17.

I have tried with

mvn serenity:aggregate -DHOST=$HOST -Dreport.customfields.ApplicationVersion=1.2.4 

command as well, but in vain.

Can you please let me know the way to fix this?
