Legend properties on shapes property of layouts is not being tracked by Typescript

[senese]

I'm coding with Plotly.js using the latest version of the library and its types:

package.json

  "dependencies": {
    ...
    "plotly.js-dist": "^2.26.2",
    "plotly.js-dist-min": "^2.26.2",
   }
  "devDependencies": {
    ...
    "@types/plotly.js": "^2.12.29",
    "@types/plotly.js-dist-min": "^2.3.3",
   }

And according to the print screens above, the legend properties on shapes property of layouts (Documentation) aren't tracked by Typescript Intellisense.

And also the legendgroup property don't even exists:

There is a workaround for this or a permanent fix coming?
