how to get differential peaks containing a specific motif

[ksr2018]

Hello,
I would like to get peak coordinate information (such as chr, start, end) for peaks that contain a specific transcription factor motif.
I have seen few other discussion/issues that have asked similar questions and the solution involves subsetting the seMarker. But I cannot figure out how to do that. Can someone please help with the exact code to do this?

I have run the following code. After this, how can I find which peaks in markerTest_C3vsC2 contain motifs for a specific TF such as GATA4?

###----------------DIFFERENTIAL PEAK ANALYSIS ---------------------------------------------------------------------------
markerTest_C3vsC2 <- getMarkerFeatures(ArchRProj = proj1, useMatrix = "PeakMatrix",groupBy = "Clusters",
  testMethod = "wilcoxon",bias = c("TSSEnrichment", "log10(nFrags)"),useGroups = "C3",bgdGroups = "C2")

###----------------MOTIF ENRICHMENT---------------------------------------------------------------------------------------
#proj1 <- addMotifAnnotations(ArchRProj = proj1, motifSet = "cisbp", name = "Motif", force=T)
motifsUp <- peakAnnoEnrichment(seMarker = markerTest_C3vsC2, ArchRProj = atrialcms3, peakAnnotation = "Motif",
                               cutOff = "FDR <= 0.1 & Log2FC >= 0.5")

Thank you in advance!
