Appian RPA - Custom Code developer [RPA Beginner]

Hi Appian Solutions / Appian Community , 

https://docs.appian.com/suite/help/24.4/rpa-9.16/java-module-ms-outlook.html 

I'm working on creating a custom Java code for the Appian RPA MS Outlook module. While I've finished the Java component, I'm unsure how to integrate or put those into Appian RPA. 

It would be great to get some insights on best practices and common challenges from someone with experience in this area. I tried to follow the Appian RPA documentation, but somewhere felt like lost.

Could anyone with experience incorporating custom Java code into Appian RPA offer some guidance?

Thanks,

Bharathwaj RK
