retrieve peaks associated to a gene SIGNAC

Question

[Chironex]

Hi, I would like to know how to obtain peak coordinates associated to one or more genes.

Here for example I'm able to obtain peaks included in a specific region:

overlap_peaks <- findOverlaps(seurat_obj, StringToGRanges("chr1-10000000-18000000"))  
EN= granges(seurat_obj)[queryHits(overlap_peaks)]

instead of the region I only know the gene name. Thank you
