How to config option of babel plugin in extraBabelPlugins (umi v3)

[le2tuan]

Hello guys, I'am working on this babel plugins https://babeljs.io/docs/en/babel-plugin-transform-react-jsx with some configs like

plugins": [
    ["@babel/plugin-transform-react-jsx", {
      "pragma": "h",
      "pragmaFrag": "Fragment",
    }]
  ]

But I don't know how to declare this in umi v3, I am going use this property extraBabelPlugins , but it only accept Array[string] like that

  extraBabelPlugins: [
    "@babel/plugin-proposal-optional-chaining"
  ],

Please guide me how to fix it. Many thanks

Maybe use it like this：

extraBabelPlugins: [
    "@babel/plugin-proposal-optional-chaining",
    ["@babel/plugin-transform-react-jsx", {
      "pragma": "h",
      "pragmaFrag": "Fragment",
    }]
  ],
