Custom Code setup in Appian RPA

Is it possible to get the robotic task, which is custom developed in IDE (intellij) executed in Appian RPA?

I am following the documentation on Custom code dev in Appian RPA. Using Guided configurator initial steps are completed with respect to JDK, Maven and IDE setup. After this I was reading Calculator tutorial and downloaded source code file to try and execute the custom developed bot in RPA console.

Due to being novice in Java and Maven I am not able to understand fully how the IDE connects with Appian RPA console,
- how do I get this calculator bot imported/deployed and then executed in Appian RPA.
- Do I need to create a bot in RPA first and then export it, copy it in my IDE project folder, copy calculator code and then run some deployment command or how?

Can someone simplify it for me and explain how to achieve this? If possible, please distil it down in steps.


Thanks in Advance.
