How to set the default font size for heading blocks

I can see from some online guides on how to define custom font sizes for heading blocks from my theme.json file.

"blocks": {
      "core/heading": {
        "typography": {
          "customFontSize": false,
          "fontSizes": [
            {
              "slug": "small",
              "size": "2rem",
              "name": "small"
            },
            {
              "slug": "medium",
              "size": "2.25rem",
              "name": "medium"
            },
            {
              "slug": "large",
              "size": "3rem",
              "name": "large"
            }
          ]
        }
      }
    }

…But how do we set the “default” font size for h2 heading blocks when they load onto the page for the first time. Upon inspecting it, its set to a font size of 52px, which is not any of the 3 rem sizes you see above.

Where can I modify that initial default value?
