Hi, I have aligned RNAseq data as *.bigwig

I am trying to import these bigwig files into igvR but I do not know how. I am reading through the docs but I am confused. Can somebody share a line of code and explain how I can get from bigwig to display a track?

Alternatively, I tried to create a GenomicRanges object via rtracklayer::import.bw("file/to/bigwig.bw) without success in visualizing it in igvR

Thanks
