espub: jsx transform doesn't work

We are building with the latest version.

The jsx syntax in the tsx file is expressed as it is without being built.

Is there no way?

// index.mjs

  const buttonContent = <span>{children || ""}</span>;

The expected expression is:

const buttonContent = React.createElement("span", null, children || "");

Both cjs and mjs are the same.

jsx syntax doesn’t compile.

// tsconfig 

{
    compilerOptions: {
        jsx: "react"  // not working 
        jsx: "react-jsx" // compile with jsx function 
    }

}
