How to get microbial relative contributors for PICRUSt2 result

I want to know, Is there any way to get microbial contributors for the PICRUSt2 result? After generating pathway abundance, can I trace it back to investigate microbial contributors for each pathway? Is there a command line to do that? One solution that I know, we can calculate relative contributions as the total number of copies of genes mapped to a pathway across all samples per genus over the total number of gene copies assigned to that pathway.

I am grateful for your help.
