Altair EDEM OpenFOAM coupling

Hello,

I have gone through the page given below.
https://community.altair.com/community/en/edem-openfoam-coupling?id=kb_article_view&sysparm_article=KB0122037&sys_kb_id=4f02c90cdbe6e910cfd5f6a4e29619d4&spa=1

Can someone please let me know about what's the exact process of coupling EDEM with OpenFOAM?
I use EDEM on Windows but I access OpenFOAM through Ubuntu 20.04 LTS using Windows subsystem for linux (wsl).
When I execute the simulation how would the data be generated? whats the process to post process the results?

Please let me know as to how one can couple these both to produce a coupled solution.

Thanks in advance!
