How to get bamboo build logs into bamboo notification email (last 20 lines) if build gets failed?

I am currently getting bamboo notification emails, but it doesn't have any log lines included in it, I wanted to include last 20 lines of bamboo logs into notification email once bamboo plan is completed.

 

I was going through this documentation to customize bamboo notification templates but I couldn't find how to fetch log lines into my freemarker template. Please help me with this, I'm new to both freemarker & bamboo.
