Are there annotated ICGC copy number somatic mutation files?

Question

[zhiyuan]

Hi everyone, I downloaded a copy number somatic mutation file from ICGC, but I discovered that it was not annotated (the field "gene_affected" was blank). So I want to know where can I find annotated ICGC copy number somatic mutation files, just like gene-level copy number files in UCSC Xena? Should I set the field "gene_affected" by mapping fields "chromosome", "chromosome_start", "chromosome_end" to genome annotation row by row? Fields in this file:
