Hello @hhamalai, this looks on the right path, I can have a look after you fix the CI issues? Do you want to continue on this?

[hhamalai]

Thanks for reminding me!

I fixed the linter checks, can you probably point me how to react to that "generate" step error from CI.

Currently running a few builds utilizing this solution, thanks for creating it!
