That chart shows the federal reserve assets, not the total supply of dollars. It's a pretty interesting chart, but it doesn't support the statistic you quoted.
I'm sorry, I don't have enough information on what those statistics mean. I'm not sure what that chart measures, but it shows a 4x increase in early 2020 which leads me to think it isn't saying what you think it's saying. While I don't doubt it relates to how the Fed manages the money supply, it doesn't say what you want it to say.
If you are going to sell this point, you need a source that undstands and can break down the subject matter to explain what these charts are measuring and how that relates to the supply of US currency.
