How much fees have RSK miners earned?

Saw this thread on Twitter:

It struck me that this Fee Revenue stat is likely not including fees from RSK merged mining. I think this is an important number to include, and will likely be increasingly important if/as RSK gains adoption. Is anyone tracking how much RBTC RSK miners are earning from transaction fees? I’d be particularly interested in a chart that can switch between 24h, 7D, 1M, 1Y, All Time.
