Metaspade assembled contig to metaphlan

Hi everyone
I am very new to WMS and metaphlan, I have six samples (fastq).
My question is can I assemble the reads using metaspade or megahit and import and analysis in metaphlan3.

Because I read a paper that assembled reads shows more taxonomic resolution.

Sorry if my qs is work, just an idea, Please anyone clear this issue.

Thank you for your valuable time

Thank you
