How can I get the plugin MarketPress LIte for CoursePress?

Hey
I hope you having a wonderful day.
Let me ask a question.

I am searching to find the plugin MarketPress LIte for CoursePress Pro, because I will use the feature of this is for only CoursePress Pro.
However, I can't find this.

Normal Version of MarketPress is too much for this use.

So could you tell me where is MarketPress Lite for CoursePress Pro?

Best Regards
