How to use MACS2 output for DESEQ2 differential analysis during ATAC-seq? How to get the intersect?

I have processed my ATAC-seq reads and finally obtained MACs2 output bed files.
I am at a loss to proceed from here to DESeq2 analysis. I will be thankful to you if could briefly explain the way to process the reads to use them for DESeq2 analysis.
